Investigation of Antimicrobial Activity of ‎Plant-Mediated Green Synthesis of Silver ‎Nanoparticles

For the past couple of years, the synthesis of silver nanoparticles via the green route had gained much attention due to its cost-effectiveness and eco-friendly technology. Here we report for the first time, to the best of our knowledge the synthesis of silver nanoparticles from aqueous leaf extract of Curcuma Caesia plant and investigated its antimicrobial activity. The bio-reduced silver nanoparticles were characterized using UV-Visible spectroscopy, FTIR, XRD, TEM, and SEM. XRD showed the crystalline nature of nanoparticles, observed peaks (111), (220), (200), and (311). The formation of AgNPs is confirmed by recording the UV–vis absorption spectra for surface plasmon resonance (SPR) peak (∼446 nm). The antimicrobial examination of the silver nanoparticles shows great antibacterial action because of high zones of hindrance against test microscopic organisms.
