Introduction

Thinking about the commonness of different diseases, infections brought about by any type of microorganism ought not to be messed with; they can go through fundamental changes and cause serious medical problems. Antimicrobial resistance is quickly becoming one of the most severe medical problems of current day 1-3. Even after significant advancements in antimicrobial therapy, infectious diseases triggered by microorganisms remain a major public health issue owing to the rise of susceptibility to currently accessible antibacterial medications 4. Bacterial resistance to a wide variety of antimicrobial drugs is becoming a leading health concern 5, 6. Antibiotics are substances that are used to destroy bacteria that can Bacterial resistance to a wide variety of antimicrobial drugs is becoming a leading health concern 5, 6. Antibiotics are substances that are used to destroy bacteria that can cause life-threatening conditions 7, 8. In light of these pressing concerns of modern time, it is critical to establish new antimicrobial agents that are more selective and reliable in their antimicrobial potential 9, 10.

Numerous antimicrobial agents are targeted and developed in order to tackle the problem of antimicrobial resistance11-13. Organic chemists are targeting the synthesis of variety of potent heterocyclic compounds and are also successful in developing new antimicrobial agents 14-20. However, research from last ten years has proved that the AgNPsare proved as potent antimicrobial agents 21-25. From ancient times, it has been established that silver is a very good medicinal elements. From this perspective researchers have adopted many bio strategies based on plants to develop more powerful antibacterial AgNPs 26, 27. To their credit, AgNPsare synthesized by various green approaches with good efficacy in the antibacterial action29, 29. Through use of silver as an anticancer and antibacterial agents has developed exponentially 30, 31. It has been proved that various plants contain organic compounds that are capable of producing AgNPs from silver salts 32, 33. Plant extracts such as stem, root, nuts, bark, and marine bioresources are among the numerous green resources used for the synthesis of AgNP’s. The extracts obtained from plants are found to be the best alternative for the synthesis of AgNP’s due to their easy accessibility, nontoxic quality, and inclusion of exceptional bioactive compounds with high therapeutic attributes.Plants are being used in the synthesis of AgNPs, and particles of various shapes and sizes have indeed been produced.Given the significance of the above reasons, this review article focuses on antibacterial applications of biosynthesized AgNPsthat have been studied over the last decade. The antimicrobial ability of AgNPs against a wide spectrum of bacteria is addressed.

Biosynthesis and Antibacterial Properties of AgNPs

The therapeutic potential of AgNPs in treating diseases is promising in the realm of bio-Nano medicine. AgNPs are candidates for ground-breaking applications in the biomedical industry as antibacterial, antifungal, antioxidant, and anticancer agents due to their small stature, large surface area, and chemical characteristics, and these applications are well established. The traditional chemical methods were used to generate nanoparticles, however, this methodologies are connected with dangerous materials that are unsafe.

Plant-mediated biosynthesis of nanoparticles, on the other hand, is growing rapidly owing to its low toxicity, resource efficiency, eco-friendliness, and quickness.Plants based natural sources include bioactive compounds such as flavonoids, proteins, polysaccharides, polyphenols, terpenoids, tannins, alkaloids, ketones, aldehydes, amines, etc., which function as reducing, bolstering, and capping agents in the transformation of metal ions to metal nanoparticles, resulting in the generation of desirable nanoparticles with preconfigured characteristics.Among the several biosynthesized metal nanoparticles, AgNPs were selected as the favourites in the realm of antibacterial applications. In the following sections, we’ll go over some of the best instances from 2015 to 2020.

Year 2015

The selected examples (year 2015) of antibacterial applications of biosynthesize AgNPs is given in Table 1. Saravana kumaret al.34 reported, the biosynthesis of AgNPs using Cassia tora leaf extract. This is an easy, cost-effective, fast, and environmentally friendly way to make AgNPs that can be accomplished in a short while. Furthermore, this process could be used at room temperature. This method yielded spherical AgNPs with well-defined characteristics which were uniformly polydispersed with face centered cubic geometry.Importantly, no capping agent was used in the AgNP synthesis. Gram positive (S. aureus, B.subtilis) and Gram negative (E. coli, P. aeruginosa) bacteria were tested for antibacterial activity. Gram negative bacteria were shown to have a larger inhibitory effect than Gram positive bacteria in their research. Miri et al. 35 used Prosopis fracta leaves extract to demonstrate a green, simple, and single-pot process for the biosynthesis of antibacterial AgNPs.This method is fast, reliable, and environmentally friendly, and it can be used to make all sorts of metal nanoparticles from a wide range of extracts. The obtained AgNPs had a spherical form, with a mean diameter of about 8.5-11 nm, according to spectral analysis.These findings show that organic biomolecules in Prosopisfracta extract showing reducing as well as capping nature.The antimicrobial action of Ag- NPs was tested against S.aureus, B.subtilis, and E.coli, P.aeruginosa. Antibacterial activity was comparable to that of the control group. According to Kokila et al. 36, AgNPs were produced via the direct interaction of silver nitrate with Cavendish banana peel extract in aqueous media, without the use of any external reagents. As a result, this reaction pathway satisfies all of the requirements for a completely environmentally friendly chemical process. The antibacterial effect of synthesized AgNPsdisplayed high antimicrobial activity against S.aureus, B. subtilis, K.pneumonia and E.coli.

The defined AgNPs demonstrated a more effective antibacterial property. The presented AgNPs showed a more compelling antibacterial effect against E. coli, K. pneumonia, S. mutans, E. faecalis. Bose et al. [38] reported a very quick, efficient, cost-effective, and environmentally friendly approach for AgNP biosynthesis using leaf extract of Psidiumguajava that showed capping as well as reducing behaviour. Because of its well-known therapeutic benefits and the fact that it is freely available throughout the year and in all seasons, this plant was chosen for this study. They usedUV–vis and TEM experiments to confirm teAgNPs. The AgNPs’ size was obtained in the 10–90 nm range. According to TEM results, the AgNPs were in spherical form.

The XRD predicted a particle size of 25 nm. Bacterial strains like S. aureus, B. cereus, S. typhimurium and E. coli were examined for evaluating the antibacterial potential of AgNPs. The antimicrobial activity of the biosynthesized nanoparticles was impressive.Benakashaniet al. [40] examined Capparisspinosa leaves as reducing extract for the synthesis of AgNPs. Using C. spinosa extract, AgNPswere successfully synthesised, and the nature of the synthesised nanoparticles was investigated using various analytical techniques. Bacterial strains like E. coli, S.typhimurium, S.aureus, and B. cereus, were used to assess the antibacterial effects of NPs provided by C. spinosa. In comparison to ionic silver, the synthesised AgNPs displayed excellent antibacterial and antimicrobial activity based on disc diffusion performance. Ananda lakshmi et al. 41 have reported the synthesis of AgNPs using Pedalium murex leaf extracts with dual functions, as well as antimicrobial effects of synthesised AgNPs against Escherichia coli, Klebsiellapneumoniae, Micrococcus flavus, Pseudomonas aeruginosa, Bacillus subtilis, Bacillus pumilus, and Staphylococcus aureus. The particle size ranged from 20 to 50 nanometers, and the crystal structure was fcc. The biosynthesized AgNPs’ antibacterial activity was found to be effective.

A.J. Kora et al. [51] have exploredthe antibacterial activity of AgNPsrendered from gum kondagogu (5 nm) against S. aureus, P. aeruginosa, E. coli bacterial species.To investigate the route of antibacterial action of AgNPs, a systematic exploration was done by this group of reseachersusing various susceptibility assays. In their investigation, the biogenic AgNPs were discovered to be more active antibacterial agents. The nanoparticles demonstrated strong anti-biofilm action against test strains at 2 g mL1, suggesting that they could be used to treat biofilm-related drug-resistant bacterial illnesses. Their discoveries checked the job of responsive oxygen species and layer harm in the antibacterial movement of silver nanoparticles. In light of their promising antibacterial activity, AgNPs could be used in a number of environmental and medicinal applications. N. Sanchooli and colleagues 52 acquired AgNPs were gotten by combining silver nitrate  and V. officinalis leaf separate. To characterise the synthesised AgNP, they used various analytical techniques. The anti-biogram and lowest inhibitory concentration of the nanoparticles produced were determined using agar well diffusion and broth micro dilution, respectively.V. officinal is AgNPs showed broad spectrum antibacterial action according to their findings. M.E.T. Yazdi et al.53 published their findings on the manufacture of AgNPs from Rheum turkestanicum aqueous shoot extract at room temperature, as well as antibacterial activity against human pathogenic bacteria. Biosynthesized AgNPs were observed to have prevalent antibacterial action against human pathogenic pathogens. Based on their findings, this process can be used to make large-scale preparations of other noble metals for a variety of purposes.

The selected examples (year 2019) of antibacterial applications of biosynthesize AgNPs is given in Table 5. S.O. Aisida et al. [54] utilized a fluid concentrate of new leaf of Gongronema Latifolium (FLGL), a herbaceous blooming plant, as a fuel specialist in the biogenic union of AgNPs. Using varying AgNO3 concentrations and a set amount of FLGL, the characteristics of produced AgNPs were examined.Using solid agar plates enriched with varying doses of nano-sized AgNPs, antibacterial action of AgNPs was exhibited on E. coli and S. Aureas bacterial strains.According to the varied characterizations of AgNPs, the difference in AgNO3 concentration as well as the incubation duration had a vital influence in regulating particle sizes and dispersions. Their investigation of the XRD uncovered single-phase crystalline structures with diameters ranging from 9 to 31 nm. According to their SEM and TEM analysis, the produced AgNPs have a spherical shape with a bioactive chemical coating and 19 nm diameter for the greatest concentration. They discovered that the inhibiting region had a stronger bactericidal effectiveness than Ciprofloxacin against bacterial strains (the positive control).

V. Ravichandranet al. [55] reported theeco-friendly synthesis of AgNPsthat was accomplished using Parkiaspeciosa leaf aqueous concentrate for the bio-source-reduction of silver ions.To validate the synthesis of AgNPs, the researchers employed UV–Vis spectroscopy. The highest absorbance of the synthesised AgNPswas observed at 410.5 nm using spectrophotometry. The extent of leaf extract, pH, temperature, silver nitrate concentration, and time, had been all spectrophotometrically tuned.The average particle size of AgNPs was confirmed by SEM, TEM, and DLS analysis, and was determined to be 31 nm, 35 nm, and 155.3 d.nm,respectively. The antibacterial studies against S.aureus,E. coli, P. aeruginosa, and B.subtilis), were significant. The suggested approach for production of AgNPs utilising Parkiaspeciosa leaf extract is both environmentally benign and practical.O.T. Jemilugba and colleagues [56] have introduced interestingly a basic, green, savvy, and harmless to the ecosystem procedure for the production of AgNPsusing Combretum erythrophyllum plant leaves’ aqueous extract. UV–Vis, TEM, FT-IR), XRD, and DLS methods were used to characterise the Ag-NPs that were generated. The particles were round fit and equitably dispersed, as indicated by the TEM picture, with an particle size of 13.62 nm.  S. aureus, S.epidermidis, E. coli and P. vulgaris pathogenic were used to check the antibacterial potential. The combined Ag-NPs were powerful against S. epidermidis and other Staphylococcus species involved in different dermatological diseases, rather than streptomycin, which was inadequate against S. epidermidis and other Staphylococcus species associated with other dermatological contaminations.

Year 2020

The selected examples (year 2019) of antibacterial applications of biosynthesize AgNPs is given in Table 6M. Gomathiet al. [57] have reported green synthesis of AgNPs(Ag NPs) using aqueous reducing leaf extract of Gymnemasylvestre. The band at 442 nm in their UV–visible absorption studies obviously demonstrated the creation of Ag NPs in the aqueous medium. The XRD spectral studies revealed that the synthesised samples possessed fcc structure, and the EDX research additionally checked the presence of Ag metal NPs by the energy top at 3 keV. According to TEM analysis, most of the created Ag NPs were circular fit, with a size of 20 to 30 nm.The biomolecules involved in the reduction process in Gymnema sylvestre plant extracts were assessed using FT-IR. The integrated Ag NPs showed high antibacterial viability against S. aureus and E. coli in their examination.

M.A. Ahmad and his colleagues58 studied the environmentally friendly synthesis of AgNPs using Muntingiacalabura leaf extract as reducing and stabilising agents, as well as the antibacterial properties of the AgNPs generated. The generation of AgNPs was monitored using a UV-Vis spectrophotometer. The size and form of AgNPs were determined using TEM. The elemental analysis was interpreted using EDS. In a microbiological inhibition assay, muntingia leaf mediated AgNPs suppressed the development of Escherichia coli and Bacillus cereus, as shown by the existence of an inhibition region. The green synthesis of AgNPs as antibacterial agents was described by M.L. Guimares et al. [59]. They used Ziziphus joazeiro leaf extract as a green reaction medium for the production of AgNPs. At neutral pH, they obtained particles with a smaller size and a lower aggregation degree. S. aureus and E. coli were used to test the antibacterial activity.A. Nouri and colleagues [60] used Menthaaquatica leaf extract as a capping and reducing agent to synthesise ultra-small AgNPs utilising a green biogenic approach. Biosynthesized AgNPs were characterised using a variety of analytical techniques. Their findings showed that using ultrasound throughout the synthesis process can result in smaller AgNPs with improved antibacterial activity.

Conclusion

In summary, this review article addresses the antibacterial uses of biosynthesized AgNPs that were investigated between 2015 and 2020. AgNPs’ antibacterial potential against a wide variety of microorganisms is discussed. AgNPs appear to be frequently used as an antibacterial agent against E.coli and S. aureus bacterial strains, according to our study.This review will be beneficial in the development of antibacterial agents based on biosynthesized AgNPs.
