Biswash Sapkota and Grinsun Sharma*

ABSTRACT

Silver is nontoxic, safe inorganic agent used for management of wounds and ulcer. It has wide range of application in form of nanoparticles. Synthesis of silver nanoparticles through cost effective and environmental friendly method is of great concern. This review focuses on green synthesis of silver nanoparticles from fruits. A detailed study of synthesis of silver nanoparticles from various fruit extracts was demonstrated. Synthesis was observed as a colour change of the mixture. The X-ray diffraction patterns, UV-visible spectrum, scanning electron microscope, transmission electron microscope, fourier transform infrared spectroscopy were used for characterizationof Silver nanoparticles. Antibacterial activitiy of Silver nanoparticles was observed against Gram-positive and Gram-negative bacteria. Various informations on synthesis, characterization techniques, properties and application of Silver nanoparticles are summarised and critically discussed in this review.

Keywords: Antibacterial, Green Synthesis, Silver nanoparticle.
