Review on Biosynthesis of Silver Nanoparticles and Its Characterization

K. Anandalakshmi¹

Abstract: The present review focused the biosynthesis of silver nanoparticles (AgNPs) using plant, bacteria and fungi. Green route of AgNPs could be provided the advantage over the physical and chemical synthesis methods. The conventional methods for the production of NPs were expensive, toxic and non-environment friendly. To overcome these problems, many researchers had been found the precise green route. This review described the methods of green synthesis of silver nanoparticles and their mechanism of antibacterial a… Show more

A new biologically active Allelochemical 3,5,7,3’,4’-pentahydroxyflavone-3-O-β-D xylopyranosyl -(1→4)- β-D-glucopyranosyl-4’-O-α-L-arabinoside (A1) whose m.p. is 340–345 0C, m.f. [M+] 728 (EIMS) was isolated from methanolic leaf extracts of Dalbergia paniculata Roxb. It was characterized by several color reactions, spectral analysis FTIR, 1H-NMR, GC-MS, and chemical degradations. The results of the antimicrobial activity of (A1) at high concentration (100µg/mL) was 20, 17, and 15 mm zone of inhibition against E. coli, B. cereus, and S. aureus aeruginosa, respectively. The data demonstrated that the antimicrobial activity of CH3 OH soluble fraction (A1 ) at all concentrations was highest against E. coli and lowest S. aureus. E. coli, B. cereus, and S. aureus aeruginosa, respectively 7.3, 2.1, and 0.02mm, MIC was defined as the minimum concentration of assayed samples that inhibited the visible growth of the tested microorganism. MIC in E. coli, B. cereus, and S. aureus aeruginosa was 7.3, 2.1, and 0.02mm, respectively.

Silver and silver salts have been used since the beginning of civilization, but silver nanoparticles (Ag NPs) have just recently been discovered. They have been employed as antioxidants and antibacterial, antifungal, and potential anticáncer agents in agriculture and medicine. Many bacteria, including Bacilluscereus, Staphylococcus aureus, Citrobacter koseri, Salmonella typhii, Pseudomonas aeruginosa, Escherichia coli, Klebsiella pneumoniae, Vibrio parahaemolyticus, and the fungus Candida albicans, were shown to be inhibited in their growth and multiplication by binding Ag/Ag+ to biomolecules that are present in microbial cells. Ag NPs are thought to create reactive oxygen species and free radicals, which cause apoptosis, cell death, and hinder cell reproduction. Ag NPs diffuse in side cells and break because they are smaller than bacteria. The researchers have developed numerous methods of their synthesis. The present review focused on the latest evidence related to silver nanoparticles, several methods of preparations, along with examples listed in the literature.
