Green Synthesis and Characterization of Silver Nanoparticles Using Rivea hypocrateriformis Leaves Extract

ABSTRACT This investigation delves into the eco-friendly production of silver nanoparticles utilizing an extract derived from Rivea hypocrateriformis leaves, serving as both a reducing and stabilizing agent. The commencement of the procedure involved validating visual assessments, showcasing the transformation in color of the reaction mixture from a light yellow hue to brown, ultimately culminating in a blackish-brown shade, serving as a clear indicator of the successful formation of nanoparticles. Characterization of the synthesized silver nanoparticles through UV-Visible spectrophotometry revealed a distinct surface plasmon resonance (SPR) band at 450 nm, confirming their metallic nature. Fourier Transform Infrared Spectroscopy (FTIR) analysis identified functional groups in both the plant extract and silver nanoparticles, providing insights into their roles in reduction and stabilization. Scanning Electron Microscopy (SEM) displayed well-separated, spherical nanoparticles with an average size ranging from 15 to 60 nm. This study establishes R. hypocrateriformis as a promising source for environmentally friendly synthesis of silver nanoparticles, opening avenues for applications in various fields, including medicine and industry.
