Abstract

The aim of the present study was a synthesis of silver nanoparticles using air-dried fruits of Diospyros malabarica extract and antibacterial activity of selected bacteria. The results of the synthesis of nanoparticles were observed by bioreduction of silver when the mixture (AgNO3 + extract) changed its color from yellow colour to dark brown. Anti-bacterial activity of silver nanoparticles synthesis from D. malabarica fruits have shown active against Pseudomonas aeruginosa and S. aureus respectively.
