Microwave assisted green synthesis of Zinc oxide nanoparticles for biological applications

Abstract

In this present study, the effect of Senna auriculata flower extract on physical and biological features of ZnO NPs prepared using microwave irradiation method is reported. Crystalline size and morphology were analyzed using x-ray diffraction and scanning electron microscope. The addition of Senna auriculata flower extract reduces the particle size more. Furrier transform infra-red technique was used to confirm the bonding between metal (Zn) and oxygen (O). Such green synthesized antibacterial agents locally destroy bacteria (Escherichia coli), without being toxic to the surrounding.
