Abstract:
Zinc nanoparticles (ZnNPs) was experimentally synthesized by employing Calotropis procera leaves extract having particle size of 12.08 nm. The color of the ZnO / Calotropis procera extract solution changed from colorless dark orange brownish. Three infrared bands are observed at 3468 cm^-1, 1646 cm-1, 1204 cm^-1, and 408 cm^-1, indicating the presence of proteins as capping agent for Zinc nanoparticles. The antimicrobial action of green synthesized ZnNPs was studied against Escherichia coli using agar plate method. As compared to control which showed 35 % zone of inhibition, the green synthesized nanoparticles significantly increased the zone of inhibition to 49 %. The research findings exhibited that ZnNPs revealed a strong antibacterial action and hence might be propagated as a new molecule having antimicrobial action for the curing of bacterial infection including multidrug resistant bacterial infection.
