NOVEL SYNTHESIS OF NANOPARTICLES CATALYZED BY IMIDAZOLIUM IONIC LIQUIDS, THEIR CHARACTERIZATION AND ANTIBACTERIAL ACTIVITIES

Nanotechnology is an escalating field that has made its contribution to all spheres of human life. Conventional synthesis of nanoparticles are complicated and suffer from serious problems like high temperature, poor yield, longer reaction time, and use of toxic and highly sensitive compounds. The green synthesis of nanoparticles has paved for better methodologies and approaches in the medicinal field. The present paper explores the synthesis of stable CdS and ZnO nanoparticles using imidazolium based ionic liquids as green solvents. Size controlled CdS and ZnO nanostructures with distinct morphologies have been successfully synthesized and this process was found to be simple, fast and feasible. Higher level of crystallinity with high intense peak and no contamination of CdS and Zn(OH)2 or other components were proved from the XRD analysis of synthesized CdS and ZnO nanoparticles. The as synthesized nanoparticles were screened for their anti-microbial activities and found that they possess significant antimicrobial activity and have the potential to act as a new antimicrobial agent and their activity may be enhanced in combination with other antimicrobial agents. Keywords: ZnO nanoparticles, CdS nanoparticles, ionic liquids, antimicrobial activity, scanning electron microscopy.
