Abstract: Kappa-carrageenan, a natural polymer that is a product derived from seaweeds has been gaining vast attention on researches because of its biodegradability and low cost production. On the side, Nanotechnology, the emerging Science of nanoparticles has been indulging the world with its new approaches on improving the characteristics of the medium used. This study differentiated the physicochemical properties of the films without and with the incorporation of zinc oxide nanoparticles (ZnOnps) to kappa-carrageenan (kc). Materials and Methods: Incorporation of ZnOnps to kc was prepared, the physicochemical properties: moisture content, degradation time, structural composition, and surface morphology were differentiated between bio composite films with and without the ZnO nps. Results and Conclusion: After several tests, zinc oxide nano particles incorporated to kappa-carrageenan exhibited some changes to its physicochemical properties, that is the lowering of moisture content and longer degradation time was observed; using SEM magnifications ZnOnps was seen in the surface of the biocomposite film. However, structural composition analysis showed that no new formation of the functional group was seen. The biocomposite films could be a substitute with the existing drug capsule because of its longer decomposition, low water content and secured safety of the drug's quality.

This study which designed to evaluate the inhibitory effect of Ethanolic extract of (Quercusrobur) and Zinc oxide nanoparticles on the growth of one genus of enterobacteriacae (Salmonella). In vitro. For this purpose graduate concentrates for plant extract (50, 100, 200, 400 )mg/ml which prepared and compared with Zinc oxide nanoparticles of different concentration (2, 1, 0.5, 0.25) μg/ml,and examined. The result showed that the studied medicinal plant has antibacterial activity against this bacteria which used. The result showed that the plant has good activity in decrease the growth of this bacteria. The results of the study also showed that the nano-ZnO has very effective antibacterial action against the studied bacteria which was Salmonella,nanoparticles concentrations lead to increasing in the inhibition zones of tested bacterial growth. We also study the effect of three antibiotics Lomefloxacin (LOM), Ciprofloxacin (SIP) and Rifampin (RA) and the result showed,in a comparison within the tested bacteria,Salmonella had a significant inhibition increase in Lomefloxacin ; the ciprofloxacin showed effect on tested bacteria. However,Rifampin does not show any effect on tested bacteria.
