Abstract
Silver nano-particles (AgNPs) were prepared by biosynthesis method and the prepared AgNPs were tested towards anti-microbial activity. Powder X-ray diffraction (XRD), scanning electron microscope (SEM), transmission electron microscope (TEM), ultraviolet–visible spectroscopy (UV-Visible) and Fourier-transform infrared spectroscopy (FT-IR) analysis were used to test the resultant AgNPs. TEM and SEM results revealed the formation of spherical shape of AgNPs. The powder XRD result implies the average particle size of AgNPs was 18 nm. The anti-microbial activity of the AgNPs was tested against several gram negative and gram positive bacteria. The anti-bacterial activity of ampicillin was found to be increased when it is companied with the present AgNPs. The investigation of antimicrobial effect against human pathogens revealed the greater efficacy of AgNPs.
