Abstract

In this study, simple approach was applied for synthesis of silver nanoparticles using Limonia acidissimia aqueous and hydro alcoholic bark extract. Controllable silver nanoparticles were developed by green approach using extract of bark of Limonia acidissimia tree. Due to presence of pytochemical compounds such as saponins, phenolic compounds, phyto sterols and quinines present in extract act as reducing agent, hence silver nanoparticles were easily produced under mild conditions. The formations of silver nanoparticles were verified by UV- visible spectroscopy. Highly stable silver nanoparticles were produced using bark extract. UV – visible spectrophotometer showed absorbance peak in range of 400-500 nm range. Only 15 minutes were required for the conversion of silver ions into silver nanoparticles at room temperature without the involvement of any hazardous chemical.

Nanoparticles

Nanoparticles are defined as particulate dispersions or solid particles with a length within the variety of10-1000nm. The drug is dissolved, entrapped, encapsulated or connected to a nanoparticle matrix. Depending upon the method of training, nanoparticles, Nano spheres or Nano capsules can be received. Nano capsules are systems wherein the drug is restricted to a hollow space surrounded by using a completely unique polymer membrane, even as Nano spheres are matrix structures wherein the drug is bodily and uniformly dispersed. In recent years, biodegradable polymeric nanoparticles, specifically those covered with hydrophilic polymer along with poly (ethylene glycol) (PEG) called long-circulating particles, had been used as potential drug transport devices because of their ability to flow into for a extended length time goal a particular organ, as companies of DNA in gene therapy, and their potential to supply proteins, peptides and genes.[8][9][10][11]

The essential goals in designing nanoparticles as a shipping device are to manipulate particle size, surface homes and release of pharmacologically energetic agents a good way to acquire the web site-unique action of the drug at the therapeutically top-rated price and dose regimen. Though liposomes had been used as ability companies with unique advantages which include defensive drugs from degradation, focused on to website online of movement and discount toxicity or side effects, their applications are restricted because of inherent issues such as low encapsulation performance, speedy leakage of water-soluble drug inside the presence of blood components and poor garage stability. On the alternative hand, polymeric nanoparticles provide a few unique blessings over liposomes. For example, they help to growth the stableness of medication/proteins and possess beneficial controlled release houses.[12][13]

Advantages

The benefits of using nanoparticles as a drug shipping system consist of the following:

1. Particle size and floor characteristics of nanoparticles can be easily manipulated to gain both passive and active drug concentrated on after parenteral management.

2. They manipulate and maintain launch of the drug at some stage in the transportation and on the website of localization, altering organ distribution of the drug and subsequent clearance of the drug to be able to gain growth in drug healing efficacy and discount in side effects.

3. Controlled release and particle degradation traits can be without difficulty modulated by using the selection of matrix ingredients. Drug loading is fairly excessive and drugs can be incorporated in to the systems with none chemical response; that is an vital issue for maintaining the drug pastime.

4. Site-particular focused on may be achieved by attaching targeting ligands to surface of debris or use of magnetic guidance.

5. The device can be used for numerous routes of administration such as oral, nasal, parenteral, intra-ocular and many others.

Limitations 

Nanoparticles do have some limitations. For instance, their small length and huge surface vicinity can result in particle particle aggregation, making bodily dealing with of nanoparticle shard in liquid and dry bureaucracy. In addition, small particles length and massive surface vicinity easily bring about restrained drug loading and burst launch. These sensible problems ought to be conquer earlier than nanoparticles can be used clinically or made commercially to be had. The present evaluate information the contemporary improvement of nano particulate drug transport structures, floor change issues, drug loading strategies, launch manipulate and ability programs of nanoparticles.

Silver Nanoparticle

Silver nanoparticles (AgNPs) are increasingly used in various fields, including medical, food, health care, consumer, and industrial purposes, due to their unique physical and chemical properties. These include optical, electrical, and thermal, high electrical conductivity, and biological properties.[14][15][16]

Due to their odd properties, they had been used for several applications, which include as antibacterial retailers, in business, household, and healthcare-associated merchandise, in purchaser products, medical tool coatings, optical sensors, and cosmetics, inside the pharmaceutical enterprise, the food enterprise, in diagnostics, orthopaedics, drug transport, as anticancer agents, and have in the end stronger the tumor-killing effects of anticancer drugs.[17]

Nano sized steel particles are precise and might notably exchange physical, chemical, and biological houses because of their floor-to-quantity ratio; therefore, these nanoparticles had been exploited for various purposes. [18][19]

Among several synthetic strategies for AgNPs, organic strategies seem to be easy, fast, non-toxic, reliable, and inexperienced techniques which can produce properly-described size and morphology below optimized conditions for translational research. In the cease, a in experienced chemistry method for the synthesis of AgNPs suggests much promise.

After synthesis, precise particle characterization is necessary, due to the fact the physicochemical properties of a particle could have a giant impact on their biological houses. In order to cope with the safety issue to use the total potential of any Nano material in the purpose of human welfare, in Nano medicines, or in the fitness care enterprise, etc., it is vital to signify the organized nanoparticles earlier than application.[20][21]

The biological pastime of AgNPs depends on elements along with surface chemistry, length, size distribution, form, particle morphology, particle composition, coating/capping, agglomeration, and dissolution rate, particle reactivity in answer, efficiency of ion release, and mobile type, and the sort of lowering retailers used for the synthesis of AgNPs are a critical component for the dedication of cytotoxicity. [22]

Mechanism

Although the exact mechanism of silver nanoparticles’ antibacterial effects has no longer been entirely clarified, various antibacterial moves had been proposed in Figure 3. Silver nanoparticles can usually release silver ions, which may be taken into consideration the mechanism of killing microbes. [23]

Owing to electrostatic appeal and affinity to sulphur proteins, silver ions can adhere to the mobile wall and cytoplasmic membrane. The adhered ions can beautify the permeability of the cytoplasmic membrane and lead to disruption of the bacterial envelope. [24]

After the uptake of loose silver ions into cells, respiration enzymes may be deactivated, generating reactive oxygen species but interrupting adenosine triphosphate manufacturing.[25]

Reactive oxygen species can be a foremost agent in the provocation of cell membrane disruption and deoxyribonucleic acid (DNA) modification. As sulphur and phosphorus are critical components of DNA, the interaction of silver ions with the sulphur and phosphorus of DNA can purpose problems in DNA replication, cellular reproduction, or even result in termination of the microorganisms. Moreover, silver ions can inhibit the synthesis of proteins by denaturing ribosomes within the cytoplasm. [26]


       
            Mechanism of Action.png
       

Fig No – 3 Mechanism of Action


The antibacterial moves of silver nanoparticles (AgNPs).

1) Disruption of cellular wall and cytoplasmic membrane: silver ions (Ag+) released with the aid of silver nanoparticles adhere to or bypass thru cellular wall and cytoplasmic membrane.

2) Denaturation of ribosomes: silver ions denature ribosomes and inhibit protein synthesis.

3) Interruption of adenosine triphosphate (ATP) manufacturing: ATP manufacturing is terminated due to the fact silver ions deactivate breathing enzyme on cytoplasmic membrane.

4) Membrane disruption by way of reactive oxygen species: reactive oxygen species produced by the damaged electron delivery chain can reason membrane disruption.

5) Interference of deoxyribonucleic acid (DNA) replication: silver and reactive oxygen species bind to deoxyribonucleic acid and prevent its replication and cellular multiplication.

6) Denaturation of membrane: silver nanoparticles collect within the pits of cell wall and reason membrane denaturation.

7) Perforation of membrane: silver nanoparticles without delay pass across cytoplasmic membrane, which could launch organelles from mobile.

In addition to being capable of launch silver ions, silver nanoparticles can themselves kill bacteria. Silver nanoparticles can gather inside the pits that shape on the cell wall once they anchor to the cellular surface.[27]

RESULT AND DISCUSSION

Visual observation and UV-Visible spectroscopy

In all experiments, addition of plant extract of A. indica into the beakers containing aqueous solution of silver nitrate led to the change in the colour of the solution to yellowish to reddish brown  within reaction duration due to excitation of surface plasmon vibrations in silver nanoparticles . On addition of different concentration (1e5 mL) of leaf extracts to aqueous silver nitrate solution keeping its concentration 10 mL (1 mM) constant, the colour of the solution changed from faint light to yellowish brown and finally to colloidal brown indicating formation of silver nanoparticles. Different parameters were optimized including concentration of silver nitrate and A. indica leaf extract, and time which had been identified as factors affecting the yields of silver nanoparticles. Silver nanoparticles were synthesized at different concentrations of leaf extract such as 1e5 mL using 1 mM of silver nitrate were analysed by UV spectra of Plasmon resonance band observed at 436 to 446 nm similar to those reported in literature . If we increase the leaf extract concentration to 4 mL, there is increase in wavelength. The slight variations in the values of absorbance signifies that the changes are the particle size  On increasing concentration of extract there is increase in intensity of absorption. It is generally recognize that UV-Visible spectroscopy could be used to examine size and shape-controlled nanoparticles in aqueous suspensions.

Parallel changes in colour have been observed when different concentrations (1 mMe5 mM) of silver nitrate was used by keeping plant extract (1 mL) constant. The appearance of the brown colour was due to the excitation of the Surface Plasmon Resonance (SPR), typical of silver nanoparticles having absorbance values which were reported earlier in the visible range of 446e448 nm . There is increase in intensity of absorption peaks after regular intervals of time and the colour intensity increased with the duration of incubation. It was also observed from Fig. 2b that the intensity of absorption peaks increases with increase in the concentration of the silver nitrate salt. All the results are very close already reported in literature showing absorbance at 445 nm of silver nanoparticles synthesized by Cochlospermumreligiosum extract. The UV-visible spectra recorded, implied that most rapid bioreduction was achieved using A. indica leaf extract as reducing agent. The UV-visible spectra and visual observation revealed that formation of silver nanoparticles occurred rapidly within 15 min

CONCLUSION

A simple one-pot green synthesis of stable silver nanoparticles using A. indica leaf extract at room temperature was reported in this study. Synthesis was found to be efficient in terms of reaction time as well as stability of the synthesized nanoparticles which exclude external stabilizers/reducing agents. It proves to be an eco-friendly, rapid green approach for the synthesis providing a cost effective and an efficient way for the synthesis of silver nanoparticles. Therefore, this reaction pathway satisfies all the conditions of a 100% green chemical process. The synthesised silver nanoparticles showed efficient antimicrobial activities against both E. coli and S. aureus. Benefits of using plant extract for synthesis is that it is energy efficient, cost effective, protecting human health and environment leading to lesser waste and safer products. This eco-friendly method could be a competitive alternative to the conventional physical/chemical methods used for synthesis of silver nanoparticle and thus has a potential to use in biomedical applications and will play an important role in opto-electronics and medical devices in near future.
