Abstract
Nanotechnology is widely used in the field of research in modern material science. Green
synthesis of nanomaterials is mostly emerging method of synthesis eventhough there are many chemical
methods for synthesizing the products. In the present work, biosynthesis of silver nanoparticles using
mint leaf extract is presented. This study also evaluates the antimicrobial and antioxidant properties of
silver nanoparticles from mint leaf extract. The prepared nanoparticle has been characterized by Fourier
transform infrared spectrophotometer, Scanning electron microscopy, Powder X-ray diffraction analysis
and Ultraviolet visible spectrophotometer. The synthesized silver nanoparticles showed highest
antimicrobial activity against Salmonella typhi and Klebsiella pneumonia, Aspergillus niger and highest
antioxidant activity using 1,1-diphenyl-2-picryl hydrazyl (DPPH) assay.
