Biosynthesis Of Silver Nanoparticles with The Help of Fermented Rice Water Extract Having Antimicrobial and Antioxidant Activity

This study presents the successful application of fermented rice water (FRW) extract in the renewable bioinspired green synthesis of silver nanoparticles (AgNPs). The green production of silver nanoparticles (AgNPs) was successfully accomplished using the aqueous-alcoholic extract of fermented rice. Analysis, FT-IR, XRD, FE-SEM, UV-Vis, and other physiochemical methods were used to characterize the green produced AgNPs. Plasmon resonance spectra with a maximum at 390 nm were evident in the UV-vis spectrum, and XRD verified the crystalline nature of FRW-AgNPs. FE-SEM analysis of the particles' size, shape, and morphology revealed that they were spherical in shape, with an average diameter of roughly 26 nm. FTIR was used to identify the presence of phenols or alcohols, carboxylic acids, ketones, and amine functional groups. According to in vitro biological activity investigations, the synthesized FRW-AgNPs have dose-dependent antioxidant activity against DPPH (75.2 ± 0.057) % and possible antibacterial activity against Gram (+)ve and Gram (-)ve bacteria.
