Chemical Synthesis & study of Silver Nano Particles

Jyotsna Chauhan, Varsha Rani Mehto, Tanya tiwari

Abstract


Silver nanoparticles easily interact with other particles and increases their antibacterial efficiency furthermore due to their attractive chemical, physical and optical properties has received considerable attention of the researcher. In this paper silver nanoparticles were synthesized by chemical reduction method using silver salt AgNO3 and using reducing agent NaBH4. The borohydride anions were adsorbed onto silver nanoparticles and addition of PVP prevented the aggregation of silver nanoparticles. A yellow colour was given by the silver nanoparticle solution. Different characterization techniques were performed to analyze the properties of the synthesized silver nanoparticles.
