Environmentally Friendly Synthesis and Antimicrobial Activity of ZnONPs

Abstract

The use of nanotechnology in the textile industry has increased rapidly. This is mainly due to the conventional methods used to impart different properties to fabrics often do not lead to permanent effects, and will lose their functions after laundering or wearing. Nanoparticles can provide high durability for treated fabrics, with respect to conventional materials, because they possess large surface area and high surface energy that ensure better affinity for fabrics and lead to an increase in durability of the textile function. Various methods have been employed to improve the size and property of the Zinc Oxide Nano Particles (ZnONPs) so as to enhance the performance of ZnONPs based material. Biological methods for nanoparticle synthesis using microorganisms, enzymes, and plants or plant extracts have been suggested as possible eco-friendly alternatives to chemical and physical methods. In this work, ZnONPs have been synthesized by reduction of Zinc Nitrate in plant extract and study the antimicrobial activity of synthesized ZnONPs. FT-IR spectra peak at 483 cm-1 indicated characteristic absorption bands OF ZnO nanoparticles. UV-Vis absorption spectrum showed a typical spectrum for ZnO nanoparticles. The SEM and AFM image shows that ZnONPs prepared in this study are spherical in shape with smooth surface have size of minimum 16nm to maximum 36 nm and it also shows excellent inhibition to gram positive and gram negative bacteria.
