GREEN SYNTHESIS OF SILVER NANOPARTICLES USING THE LEAF EXTRACT OF ARGYRIA NERVOSA AND ANTIMICROBIAL STUDIES
AbstractThe green synthesis of silver nanoparticles (AgNPs) gained interest and attracted to many researchers due to physical, optical, chemical and biological properties, enhancing a range of activities such as antibacterial, antifungal, anti-inflammatory and anticancer us activity. The purpose of this study is to synthesize and characterize silver nanoparticles from fully expanded leaves of Argyria nervosa as well as to test their effectiveness in antibacterial activity. In this study, at 0.1 mM concentration of silver nitrate (AgNO3), stable AgNPs were synthesized and authenticated by monitoring the colour change of the solution from yellow to brown, which was confirmed with spectrophotometric detection of optical density. The crystalline nature of these AgNPs was detected through an SEM, EDX and FTIR pattern. AgNPs were characterized through a Scanning Electron Microscopy to study the morphology of the nanoparticles. AgNPs obtained showed significantly higher antimicrobial activities against Escherichia coli (E. coli) and Bacillus sp. in comparison raw plant extracts.
