ANTIMICROBIAL ACTIVITY OF SUPPORTED METAL NANOPARTICLES: SILVER NANOPARTICLES

Abstract

Ag nanoparticles are used in antimicrobial applications as Ag ions has antimicrobial activity synthesis of Ag nanoparticles in solution phase chemical reduction of AgNO3 with NaBH4 in presence of GO suspension.The size and shape of the Ag nanoparticles are dependent on the concentration of Ag salt.The nanoparticles of different shape such as spherical, triangular, pentagonal, ellipsoid and rod are obtained at the higher concentration of the Ag salt.The synthesized Ag nanoparticles show good antimicrobial activity against the Gram negative bacteria E. coli and P. aeruginosa.The synthesized Ag nanoparticles can be useful for several applications in biological area as well as materials science.
