Abstract

This work deals with is the preparation of zinc oxide nanoparticles using gamma radiation within the network of PVP/ Gelatin nanogel which act as capping agent for prepared nanoparticles.Determination of particle size of prepared composite was achieved using High resolution transmission electron microscopy (HRTEM). Moreover, the the selected area electron diffraction pattern (SAED) pattern obtained from the results of HRTEM confirmed the formation of zinc oxide and zinc sulfide nanoparticles. FT-IR was used to identify and investigate the different function groups of the prepared PVP/Gelatine/ Ascorbic acid/ Glycerin embedded zinc oxide nanoparticles. Zinc nanoparticles showed a strong antibacterial activity against the growth of the tow bacteria used. The effect is more efficient against gram positive bacteria than gram negative and the most sensitive is Staphylococcus aureus. from the obtained data , the prepared poly( PVP/Gelatin/Zinc oxide ) nano composite have highly efficient toward some types of gram positive and gram negative bacteria.
