Niosomes are carriers that contain non-ionic surfactants in a vesicular form that have been presented as an innovative drug-delivery system of significant versatility due to their structural stability, biocompatibility, and drug loading capacity with various therapeutics. When comparing niosomes to standard liposomes, niosomes exhibit an enhanced physical and chemical stability, cost-effectiveness, and facility for a large-scale manufacture to be both clinically and industrially-relevant. Recent advances in formulation techniques focused on cholesterol, charge inducers, and newer surfactant combinations have initiated new methods of modulating vesicle-size, bilayer rigidity, and loading of attachment drugs, respectively. In addition, surface modifications of niosomes with ligands such as monoclonal antibodies, peptides, aptamers and folic acid, have greatly improved the ability to actively target cellular receptors, further providing site-specific delivery with improved therapeutic efficacy and a decreased potential for systemic toxicity. The inclusion of stimuli-responsive components such as pH-sensitive polymers, redox-reactive linkers, and thermoresponsive lipids have also afforded the development of smart niosome systems to trigger drug release according to pathological indicators. These characteristics have enabled niosomal applications across diverse disease models, such as solid tumors, fungal and bacterial infections, dermatological diseases, and neurological disorders. Apart from these encouraging characteristics, various translational challenges are still present, such as instability of the vesicles during storage, quick clearance in vivo, batch-to-batch reproducibility, and regulatory ambiguities. Novel strategies like PEGylation, freeze-drying, hybridization with biodegradable polymers, and utilization of scalable processes are being explored to resolve these issues. This review provides an integrative overview of recent research directions, challenges, and prospects of niosome-based targeted delivery, highlighting technological advancement as well as translational relevance. The observations made in this review will be useful for researchers, formulation scientists, and drug developers aiming to develop next-generation, patient-specific nanocarrier systems with superior specificity, safety, and clinical relevance.
Targeted drug delivery systems have changed how we treat diseases because they enable localized concentrations of pharmacological agents to be given at the site of pathology while minimizing systemic adverse effects1. These systems improve drug bioavailability, provide controlled drug release, and reduce drug degradation before reaching the target localization2. Of the many nanocarrier systems synthesized over the last few decades, niosomes have been of increased interest, given their versatility, chemical stability, and incorporation of both lipophilic and hydrophilic drugs3. Niosomes are non-ionic surfactant-based vesicles that possess a similar structure to liposomes, but niosomes have advantages in shelf-life and costs associated with manufacturing that make them more marketable for large scale manufacturing4. Niosome formulations can undergo surface modification and are stimuli-responsive, which is vital for targeted delivery and controlled release systems5. As well, niosomes are biocompatible, biodegradable, and have relatively low immunogenicity which is desirable for systemic administration6. In this review, the scientific and technological advancements in niosome-based TDDSs are discussed systematically. Focus is given to their physicochemical attributes, formulation methods, active targeting functionalization approaches, and response to internal and external stimuli. Thereafter, therapeutic uses in various clinical fields like oncology, infectious diseases, and dermatology are addressed. Finally, the paper critically assesses the current limitations and translational issues and provides insights into future trends in the clinical development and marketing of niosomal systems. This review is designed as a core resource for formulators and research scientists aiming for the creation of next-generation, patient-specific nanocarriers.
This narrative review was done with the aim of presenting an in-depth overview of recent research progress in niosome-based drug delivery systems. Pertinent literature in the form of articles published between 2000 and 2024 was accessed from databases like Scopus, Google Scholar, Web of Science, and PubMed using keywords like niosomal carriers, vesicles composed of non-ionic surfactants, site-specific drug delivery platforms, stimulus-sensitive systems, and nanocarriers. Peer-reviewed original articles, reviews, and clinical reports published in English were included according to the relevance to niosome architecture, formulation methods, targeting strategies, therapeutic uses, and translational issues. Selection was based on scientific relevance and thematic significance.
Various nanocarrier-based targeted drug delivery systems have been developed in recent decades, including liposomes, polymeric nanoparticles, solid lipid nanoparticles (SLNs), dendrimers, and micelles, each possessing certain advantages regarding stability of the drug, bioavailability, and site-specific targeting (Fig.1). Liposomes, while much researched, remain handicapped by high production costs and poor long-term stability. SLNs offer improved stability but have compromised drug loading capacity, whereas polymeric nanoparticles and dendrimers allow for accurate functionalization but issue in the case of biocompatibility and regulatory approval. Niosomes, which are vesicles composed of non-ionic surfactants, have recently gained significant attention due to their enhanced chemical stability, affordability, and ability to encapsulate both hydrophilic and lipophilic agents. Moreover, their ease of surface functionalization for ligand attachment and the integration of stimulus-responsive elements further enhance their targeted delivery capabilities. These characteristics establish niosomes as a potential next-generation drug delivery platform with enhanced prospects for clinical translation7.

Niosomes are microscopic lamellar structures (Fig. 2) formed by non-ionic surfactants and cholesterol, which assemble into bilayer vesicles within aqueous medium8. The common surfactants employed are alkyl or dialkyl polyglycerol ethers, e.g., Span (sorbitan esters), Tween (polyoxyethylene sorbitan esters), and Brij (polyoxyethylene ethers) families9. The amphiphilic structures in these molecules lead to the creation of vesicles having their hydrophobic tails inward and hydrophilic heads toward the aqueous environment, thus facilitating the entrapment of both lipid- and water-soluble drugs. Cholesterol is often added to niosomal formulations to increase membrane rigidity, decrease permeability, and stabilize the vesicle structure at physiological conditions10. Niosomes are classified by size and number of lamellae: small unilamellar vesicle (SUV) (10-100 nm), large unilamellar vesicle (LUV) (greater than 100 nm), and the multilamellar vesicle (MLV) with multiple bilayers that can be in a size range to micron diameter11. Drug loading capacity, release profiles, and in vivo distribution is affected based upon these structures. In addition to the surface charge and overall stability of colloids, charge inducers (for example, dicetyl phosphate for negative charge or stearylamine for positive charge) can be added to other ingredients to influence circulation time and biodistribution12. Beyond the overall values, the physicochemical characteristics of niosomes aid in their biological behavior and include size, surface charge, lamellar structure, and bilayer elasticity. For example, small vesicles that are neutral or have a slight negative surface charge are not quickly cleared from circulation by the MPS (mononuclear phagocyte system) providing better systemic bioavailability. Size, lamellar structure, surface charge, or drug to bilayer could be adjusted to modulate release profiles and enable targeting specific for tissue13.

Among the methods for preparing niosomes, the thin-film hydration approach is the most widely used due to simplicity and functionality. Thin film hydration, shown in Figure 3, involves dissolving cholesterol and non-ionic surfactants in a volatile organic solvent, typically a chloroform-methanol mixture, and then evaporating the solvent under reduced pressure with a rotary evaporator. This results in a thin film of lipids coating the inner wall of a round bottom flask. Hydration with an aqueous phase containing the drug then occurs, resulting in the dehydration and separation of the lipid film to produce multilamellar vesicles (MLVs)14. The size of the vesicles and the resulting lamellarity can then be manipulated post hydration by reducing the size by techniques such as sonication or by extrusion through polycarbonate membranes to generate small unilamellar vesicles (SUVs) or larger liposomes (LUVs) which can be used depending on the application15. The hydration parameters, including hydration temperature, surfactant to cholesterol (Chol) ratio, and the surfactant type are important to formulations particle size, encapsulation efficiency (EE), and stability16. This process is suitable to encapsulate both hydrophilic and lipophilic drugs. Thermolabile compounds are typically not suitable for this method because of heat produced during the film formation and hydration process. Nevertheless, its scalability, reproducibility, and high entrapment efficiency make it a staple in niosome drug delivery research and industry17. The thin film hydration techniques is a very common method for preparing niosomes due to its ease of preparation and its efficiency.

The REV approach is often employed for obtaining high encapsulation efficiency, particularly for hydrophilic materials (Fig.4). In REV, the aqueous phase solution is first sonicated along with the drug and a mixture of cholesterol and surfactants in organic solvents such as diethyl ether or isopropyl ether, which generates a water-in-oil (w/o) emulsion. On slow evaporation of the organic phase under diminished pressure, vesicles spontaneously form as the surfactant molecules rearrange themselves around the aqueous droplets18.The vesicles thus obtained are usually unilamellar of high encapsulation efficiency because the aqueous and lipid phases are intimately mixed during emulsification. Niosomes derived from REV tend to disperse more stably and reproducibly. But solvent residue concerns and organic solvent removal requirements by vacuum methods create scalability issues19.

The ether injection technique (Fig.5) consists of slow injection of a lipid solution containing surfactants and cholesterol dissolved in diethyl ether or ethanol is added into preheated aqueous drug solution under continuous stirring. The organic solvent evaporates very quickly when it comes in contact with the hot aqueous phase, and niosomal vesicles form20. This approach is appropriate for the generation of small unilamellar vesicles and provides vesicle size control by managing injection rate and temperature. Nevertheless, the application of volatile organic solvents and elevated temperatures could be limiting factors for heat-sensitive drugs. The requirement for strict temperature control and stirring conditions could also limit bulk production21.

Microfluidization and microfluidic processing (Fig.6) have become sophisticated means of continuous and scalable manufacture of niosomes with controlled size and lamellarity. These processes involve the high-pressure impingement of liquid streams or controlled microchannel mixing to induce vesicle self-assembly22. These processes impart uniform size distribution and are scalable, and thus, they are of interest for industrial manufacture. Microfluidic platforms, specifically, enable automation and real-time control of process parameters. Despite this, high equipment cost and optimization of flow rates and channel sizes are still major hindrances23.

Proniosomes are dehydrated free-flowing powders or gels that develop niosomal vesicles upon rehydration. The systems are composed of surfactants and cholesterol coated on carriers like maltodextrin or sorbitol by a solvent evaporation process (Fig. 7). When proniosomes come into contact with water or body fluids, they spontaneously rehydrate to produce niosomes24. Proniosomes resolve instability issues around aqueous niosomal suspensions, providing an extended shelf-life, ease of formulation and enhanced reproducibility. This approach is especially suited for the oral and transdermal delivery of drugs, because hydration may occur on-site after administration. While this approach does provide high encapsulation efficiency and scalability, complete hydration and vesicle formation are dependent on and variable on physiological conditions (which can vary from person to person)25.

Sonication and extrusion are supplemental methods typically used to reduce vesicle size and achieve uniformity after the initial formation of niosomes (Fig. 8). Sonication uses ultrasonic waves to break down larger vesicles into small unilamellars. The probe and bath-type sonicators are typically used, with the probe-type sonicator being more efficient, as it generates heat, which can be detrimental to sensitive drugs26. Extrusion involves passing the niosomal suspension through polycarbonate membranes with defined pore sizes under controlled pressure. This method yields vesicles with a narrow size distribution, increases batch-to-batch reproducibility. Both processes are illustrated in combination with other methods of fabrication to create slight changes in the properties of the vesicles27.

Targeted drug delivery is aimed at improving the therapeutic effect by specifically targeting drug-loaded carriers to the diseased tissue or cell, thus reducing systemic toxicity. Niosomes are promising vehicles for drug delivery systems due to their structural versatility and modifiable surface chemistry for passive or active targeting methods.
Passive targeting leverages the enhanced permeability and retention (EPR) effect, a feature of tumor vasculature marked by leaky endothelial junctions and impaired lymphatic drainage.Optimally sized niosomes (usually 100–200 nm) preferentially localize within tumor tissues via the EPR effect after systemic delivery28. Surface charge and hydrophilicity further affect circulation time; niosomes bearing hydrophilic polymer modifications like polyethylene glycol (PEG) acquire "stealth" properties by avoiding opsonization and subsequent clearance by the MPS, with extended systemic circulation and improved passive buildup at the target sites29.
Active targeting involves modifying the niosome surface with ligands that bind specifically to receptors or antigens abundantly expressed on the target cells. This enhances the cellular uptake by receptor-mediated endocytosis and enhances drug delivery intracellularly. Monoclonal antibodies, aptamers, peptides, and small molecules such as folic acid or transferrin are common targeting moieties30. In other cases, niosomes have shown to induce greater cytotoxic effects against cancer cell lines that overexpress folate receptors compared with niosomes without this targeting31. In addition to using an appropriating targeting moiety, ligand conjugation can be designed with either covalent linkers or non-covalent adsorption to create functional stability and bioactivity in a living system.
Niosomes can be constructed to respond to internal stimuli like pH change, redox condition, and enzyme action, or external stimuli like light, temperature, and magnetic fields. pH-responsive niosomes have the potential to leverage the acidic tumor microenvironment or endosomal environment to achieve targeted drug delivery with minimized off-target effects32. Redox-responsive niosomes possess breakable disulfide linkages that can be cleaved in the glutathione-abundant tumor cell environment, and enable on-demand drug release33. Thermosensitive formulations phase-separate under mild hyperthermia and enable controlled drug release in response to external thermal activation34.
Emerging trends involve the convergence of various targeting strategies into one niosomal system such as passive targeting, active targeting and stimulus-responsiveness to attain maximal therapeutic response. Such multi-functional niosomes offer enhanced selectivity, reduced systemic toxicity and better pharmacokinetic properties35.
Niosomes are a versatile nanocarrier employed in different therapeutic fields and can be easily employed for the delivery of hydrophilic and hydrophobic drugs in a controlled release form with targeted action against specific tissues. They possess inherent advantages like stability compared to liposomes and low toxicity characteristics that make them a promising addition to various clinical applications. This section describes some of the prime therapeutic applications of niosomes (Fig. 9) based on some recent advances and clinical importance.
Fig.9. Application-Specific Roles of Niosomes in Targeted Drug Delivery
Cancer remains a major cause of mortality globally, and chemotherapy is limited by toxicity, low tumor targeting, and drug-resistant tumors. Niosomes are capable of overcoming these limitations by optimizing anticancer agent pharmacokinetics and biodistribution. Due to their vesicular nature, niosomes are able to encapsulate hydrophobic drugs like paclitaxel and cisplatin or hydrophilic drugs like doxorubicin. Encapsulation in niosomes protects drugs from degradation and clearance, increasing circulation half-life36. Importantly, modifying the niosome surface with ligands that target overexpressed cancer cell receptors - such as transferrin, folate, and epidermal growth factor receptors - can enhance selective uptake by drugs using receptor-mediated endocytosis and boost intracellular drug concentrations37. Stimuli-responsive niosomes can release their drug cargo in response to acidic pH or redox conditions within the tumor microenvironment, enabling precise and controlled delivery to the target site38. These representative designs provide additional multifunctionality for reducing off-target toxicity and moving forward against multidrug resistance due to enhancing intracellular drug retention.
Delivering antimicrobial drugs to the site of action is still a challenge due to the localization of the pathogen in intracellular spaces and biofilms. Niosomes offer a solution to this challenge through the enhanced intracellular delivery of antibiotics and antifungal agents, and therefore increased therapeutic efficacy, for example, for difficult-to-treat infections such as tuberculosis and systemic mycoses. For example, rifampicin niosomal encapsulation allows macrophage preferential uptake the main host cell for Mycobacterium tuberculosis enhancing local drug concentration and lowering systemic exposure39. In addition, niosomes improve the stability and solubility of drugs like amphotericin B, thereby lowering nephrotoxicity and minimizing infusion-related adverse effect40. Disruption of biofilm architecture further enhances antimicrobial effect. Recent developments include niosomes that are targeting ligand-functionalized or stimulus-responsive structures releasing antimicrobials in a targeted manner within infected tissues to achieve maximum efficacy with minimal toxicity41.
Transdermal drug delivery is limited by the stratum corneum, which acts as a barrier and hinders the penetration of numerous therapeutic agents. Niosomes enhance drug permeation and retention within the skin, serving as an effective carrier for both local and systemic treatments via the dermal route. The encapsulation of anti-inflammatory drugs such as ketoprofen within niosomes has revealed increased drug deposition in dermis and epidermis, resulting in improved therapeutic effectiveness with decreased systemic absorption and side effects42. Niosomal delivery methods may be developed into gels or creams, for example proniosomal gels, which afford more stability and ease of use. They allow for extended delivery of drug-release and increased patient adherence in chronic diseases like psoriasis and eczema. They are less irritating and more biocompatible, which qualifies their appropriate use in treating dermatological conditions43.
Non-viral gene delivery systems are front and center in a new focus of attention that is attributed to the safety risks of viral vectors also known as viral delivery. Niosomes are multi-functional gene delivery carriers that can transmit nucleic acids to exceed the enzymatic upper limit and achieve successful cellular internalization. Niosomes can be surface modified with cationic lipids or polymers that facilitate compaction of plasmid DNA or siRNA into nanoscale nanoparticles achieving high transfection efficiency44. Niosomal gene delivery has been considered promising in the delivery of therapeutic genes for cancer immunotherapy, genetic illnesses, and regenerative medicine. The niosomal formulation has controllable release characteristics that allow for temporal control of gene expression. Localization of niosome delivery can be improved through surface modification with targeting ligands45. Research is still ongoing with the aim to augment the formulation of niosomes in efforts to achieve safe, effective, and clinically translatable gene therapies.
Although niosomes exhibit beneficial qualities as drug carriers, they are still surrounded by numerous hindrances and limitations that do not allow them to easily transfer to clinical practice and into the marketplace. Being aware of these limitations is crucial for the optimization of niosomal formulations and the development of robust and reproducible manufacturing processes. Key factors affecting clinical transfer are outlined in Table 1.

While niosomes are generally more stable chemically than liposomes, physicochemical instability can arise during storage in the form of fusion, aggregation, and leakage of the encapsulated drugs 46. The stability of the vesicle is influenced by the selection of cholesterol content, surfactant, and the preparation method. The surfactants in niosomes are vulnerable to hydrolysis and oxidation, leading to damage to the bilayer and subsequent occurrence of drug release before intended. Stabilizers and lyophilization have also been explored, but further optimization must be accomplished to guarantee that drug encapsulation efficiency and vesicle size distribution are preserved over time47.
The development of niosomes with reproducible physicochemical characteristics for large-scale production is still a critical bottleneck. Conventional preparation procedures, including thin-film hydration and sonication, are extremely time-consuming, labor-intensive, and hard to scale up to generate quantities that are commercially relevant. It is difficult to obtain homogeneous control from batch to batch with respect to vesicle size, lamellarity, and drug loading, and both the product outcome and resulting regulatory approval are affected. While microfluidics and high-pressure homogenization technologies have introduced scalable options, they need more testing and development before they are economically viable for use in commercial operations in the life sciences and pharmaceutical production arena48.
The synchronized effective encapsulation of both hydrophilic and lipophilic drugs into niosomes is a complicated task. The bilayer structure heterogeneity might restrict drug capacity for loading, particularly for bulky or charged molecules. In addition, drug release kinetics regulation to meet therapeutic needs is challenging because of passive diffusion and destabilization of the vesicles in physiological conditions. This can result in early leakage or burst release of the drug, decreasing targeting efficiency and enhancing systemic toxicity49.
After systemic administration, niosomes are quickly eliminated by the MPS, which shortens their circulation period and limits accretion at the target site50. Though surface modification with polyethylene glycol (PEGylation) can decrease opsonization and increase half-life, repeated dose administration can cause accelerated blood clearance (ABC phenomenon), rendering chronic dosing regimens challenging51. Additionally, interaction with serum proteins and the heterogeneous tumor microenvironment can hinder penetration and cellular uptake. Immunogenicity and possible toxicity with regard to surfactants and residual solvents employed in the process also require extensive scrutiny52.
The regulatory route for niosomal drug products is still less established than traditional dosage forms. Establishing stringent quality control measures, in particle size distribution, surface charge, and drug release characteristics, is indispensable for obtaining clinical approval. Additionally, thorough preclinical and clinical safety information on long-term toxicity, immunogenicity, and biodistribution needs to be presented. The lack of standardized characterization techniques and unified regulatory frameworks hinders the progression of niosomal formulations from laboratory research to clinical application53.
The technology behind niosomal drug delivery is now changing at a fast pace, fuelled by ongoing developments in nanotechnology, materials science, and molecular targeting approaches. Perhaps the brightest horizon lies in the design of multifunctional niosomes that have both therapeutic and diagnostic capabilities (theranostics). By incorporating imaging probes into the niosomal framework, scientists can track drug biodistribution and therapeutic effect in real time, facilitating personalized treatment regimens with enhanced clinical outcomes. Target specificity will be significantly boosted by surface modification of niosomes with an assortment of ligands like monoclonal antibodies, aptamers, peptides, and small molecules for targeting overexpressed receptors on disease cells. Such active targeting will enhance cellular uptake and minimize off-target effects, especially important for cancer treatment and infectious diseases. Stimuli-sensitive niosomes are another frontier that is engineered to deliver their payload upon receiving internal signals like the acidic conditions characteristic of the tumor microenvironment, variations in redox potential, enzymatic activity, and external triggers such as temperatureultrasound, or magnetism. These intelligent delivery systems allow drug delivery spatiotemporally, reducing systemic toxicity and improving therapeutic efficacy. In terms of manufacturing, scalability and reproducibility in the production of niosomes pose great challenges. Microfluidic platforms and continuous flow synthesis provide high control over vesicle size, lamellarity, and encapsulation efficiency, improving upon the limitations of the conventional batch processes. The product-independent variability assures regulatory compliance based on uniform quality of products that is conducive to clinical translation. Likewise, niosomal delivery for convergence of emerging modalities like RNA interference, CRISPR-Cas9 gene editing, and immunotherapy holds promise to treat critical conditions with an unmet medical need. In addition, the crossover with nanomedicine and artificial intelligence may reduce dosing regimens and potentially counteract patient-specific effects as a viable approach towards precision nanomedicine.
Niosomes are emerging as an effective and versatile vehicle for target-specific drug delivery because they are biocompatible, can encapsulate a wide variety of therapeutic agents, and have physicochemical parameters that can be easily modulated. They can improve upon traditional drug delivery systems by both enhancing drug stability and bioavailability, while also minimizing side effects due to targeted and controlled release. Even with these advancements towards clinical use and commercialization, there are barriers to long-term physical stability, cost-effective large-scale manufacture, and other biological barriers such as rapid clearance by the mononuclear phagocyte system (MPS) that continue to limit their use. Addressing these challenges vide rational design and innovative production technologies will unlock the clinical potential of niosomal formulations. The current review summarized recent advancements in niosome formulation research and highlighted their drug delivery applications in disease-specific therapies, while also offering a critical review of possible translational bottlenecks. The ongoing research to develop multifunctional, stimulus-responsive, and actively targeted niosomes, along with stable production methods, will accelerate the translation of these formulations to the clinic. Taken together, this research spectrum will improve approaches to safer, improved, and targeted therapeutic applications to stimulate exploration of the full niosome capability of drug delivery. Addressing these obstacles, through new formulation concepts, large-scale production economics, and wide-range safety evaluations, will be necessary for identifying optimal clinical value using niosomes. Future studies must focus on merging multifunctional targeting and stimulation sensitive release in advanced formulations to ultimately address existing delivery challenges.
