Influence of Cissus quadrangularis Stabilized AgNPs and Its Structural, Optical, Antibacterial Analysis: A Comparative Study

Silver nanoparticles (AgNPs) was synthesized by using AgCl precursor with the stabilizing agent Cissus quadrangularis by precipitation method and the obtained particles were characterized by X-ray diffraction (XRD) analysis, Field Emission Scanning Electron Microscope (FESEM) and UV–Visible (UV–Vis) analysis. The influence of a stabilizing agent on AgNPs was compared with non-stabilized AgNPs through the experimental analysis. The XRD patterns show pure face center cubic structure for both samples, whereas the crystallite size is found to be low in stabilizer used samples. FESEM image and the UV–Vis spectra show less agglomeration and blue shift respectively, for stabilizer used AgNPs, indicating small size particles. Photoluminescence spectra show the emission band at 390 nm for both samples. Antibacterial tests show good activity against Pseudomonas aeruginosa for stabilizer used AgNPs. The study concluded that Cissus quadrangularis can be used as a potential stabilizing agent for preparing AgNPs from AgCl, for optical and biomedical applications.
