Abstract :
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.
