Abstract

GREEN SYNTHESIS OF MULTIFUNCTIONAL SILVER NANOPARTICLES

Dr. R. Kanchana* and Apurva Fernandes

ABSTRACT

In the present investigation, we report the green synthesis of multifunctional silver nanoparticles (SNPs) using agro-waste material (paddy straw), a good alternative to the electrochemical methods. The synthesised SNPs were characterized by UV-visible spectrophotometry, Scanning electron microscopy (SEM) and Fourier transform - infrared spectroscopy (FTIR). UV-visible absorption scan of SNP revealed a broad peak at 420nm indicative of the surface plasmon resonance using 10 mM silver nitrate with the reaction time of 24 h. The synthesized silver nanoparticles were of size ranges from 50- 70 nm with 67%. The silver nanoparticles were investigated to evaluate the anti-microbial activity against clinical pathogens, efficacy in sewage water treatment and in biofilm degradation. The nanoparticles showed promising compatibility with these diverse functionalities which would transform it to a multifunctional nanoparticles biomedical agent potential for future clinical use.

Keywords: anti-microbial; biofilm degradation; biomedical agent; green synthesis; nanoparticle.
