Bioinspired methods for silver nanoparticle production: applications in biomedicine

This review examines the green synthesis of silver nanoparticles using Cassia auriculata   leaf and flower extracts. It outlines the extraction process, properties, and potential applications, with visual confirmation and scientific validation through UV-Visible spectroscopy, XRD, SEM, and Scherrer's formula. The AgNPs synthesized displayed unique Surface Plasmon Resonance, an optical property that enables them to produce specific colors. The further application of these nanoparticles was examined in formulating a bactericidal cold cream, which showed significant antibacterial potency against common pathogenic bacteria. The characterization of these nanoparticles spanned various technique usages, including UV-visible spectrometer, transmission electron microscope (TEM), energy dispersive spectroscopy (EDS), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) analysis, Atomic force microscopy and high-resolution transmission electron microscopy are two techniques used for analyzing complex materials.The review confirms the potential of biosynthesized silver nanoparticles from Cassia auriculata   in antibacterial formulations, emphasizing the need for further research to optimize eco-friendly processes and unlock novel applications, particularly in biomedicine.
