Abstract
Nanotechnology is the fastest growing science with broad range of applications in the field of agriculture, pharmacy, plant science, fisheries, environmental science, energy science, microbiology, electrochemical, catalysis, photon energy, space industries, textile industries, marine engineering, food and pharma industries. The synthesis of silver nano particles (AgNPs) has been proposed as a simple, eco- friendly and cost effective alternative to chemical and physical method. The present work is focused on the Galinsoga parviflora L. plant leaf mediated synthesis of silver nanoparticles for antimicrobial, antioxidant and photocatalytic applications. The synthesized siver nano particles was characterized by using ultraviolet – visible spectroscopy (UV-Vis) 300-700 nm, Fourier transform infrared spectroscopy(FTIR) in the range of 450–4000 cm−1, X-ray powder diffraction (XRD), Scanning electron microscope (SEM) analysis.
Keywords: silver nano particles, leaf extract,anti bacterial , anti oxidant
