Eco-friendly silver nanoparticles (AgNPs) have various applications in modern biotechnology for better outcomes and benefits to the society. In the present study, we report an eco-friendly synthesis of silver nanoparticles using Saraca indica leaf extract. Characterization of S. indica silver nanoparticles (SAgNPs) was carried out by Fourier transform infrared spectroscopy, scanning electron microscopy, energy dispersive spectrometry, Zeta potential, and transmission electron microscopy. SAgNPs showed antimicrobial activity against Gram-negative and Gram-positive bacteria.
In this present research work, mono and bimetallic nanoparticles are synthesized from "Rhodopseudomonas palustris KRPR01 and KRPR02." The synthesized nanoparticles are confirmed by the color change and EDX analysis. Thus, from this study, the nanoparticle synthesized from these bacterial extracts seem to be a promising and effective antibacterial agent against bacterial strains and potent antioxidant and anticancer agents. It also acts as an anticoagulant because of its hemolytic activity. Microbial synthesis being very eco-friendly and cost-effective, can be used for the large-scale integration of nanoparticles in nanotechnology processing industries and also useful in medicine, agriculture, etc.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
