Roles of pH, cation valence, and ionic strength in the stability and aggregation behavior of zinc oxide nanoparticles

The effect of zinc oxide nanoparticles ($ \mathrm{ZnO} $) on the stability and conductivity of the bilayer lipid membrane (BLM) in solution was studied. It has been shown that $ \mathrm{ZnO} $ nanoparticles increase the stability of BLM in an electric field, and BLM becomes more stable with increasing their concentration. The increase in the stability of BLM in an electrical field is mainly due to the increase in the coefficient of linear tension of the pore edge, which is forming in BLM. It is also shown, that the presence of $ \mathrm{ZnO} $ nanoparticles in the solution surrounding BLM leads to a decrease in the BLM conductivity.

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.
