In vitro mutagenicity evaluation of iron oxides nanoparticles by the bacterial reverse mutation assay. In recent years, zinc oxide nanoparticles (ZnO NPs) have gained tremendous attention attributed to their unique properties. February 2014 © Timisoara, Romania, 08 - 10 September 2011. These images demonstrated that zinc oxide nanoparticles are spherical in shape and their sizes are about 30-63nm. , Nyírő G, Szabó Z. Mutagenic activity of iron oxide nanoparticles in bacterial cells. 13. th. Their results showed minimum toxicity to mice when they were ex-posed to 50 and 500 mg/kg zinc oxide nanoparticle in diet. In this work, Zinc oxide (ZnO) nanoparticles were used to adsorb H 2 S gas at ambient temperatures. By . Applications of zinc oxide nanoparticles 41 2.9. Beef cuts inoculated with E. coli O157:H7 were As such, both prokaryotes and eukaryotes including bacteria, fungi and yeast are exploited for the synthesis of ZnO NPs by using DONYA RAMIMOGHADAM. Received 08 February 2013; revised 04 September 2013; accepted 03 December 2013 Department of Chemistry, Physical Chemistry Laboratory, S. S. J. The development of formulations of nanosized nanoparticles of titanium dioxide and zinc oxide with minimized light scattering in the visible region [27, 28], together with reports on allergic reaction to some organic UV attenuators [29], have resulted in a rapid increase of titania and zinc oxide in sunscreens. 3.4. CHARACTERIZATION OF ZINC OXIDE NANOPARTICLES AND THEIR APPLICATIONS IN FOOD SAFETY Ruoyu Li Dr. Mengshi Lin and Dr. Azlin Mustapha, Thesis Supervisors ABSTRACT In this study, ZnO NPs suspension was studied for their antibacterial activities against Escherichia coli O157:H7. Notably, evidence has shown that zinc is an important nutrient in living organisms. SEM images Zinc oxide nanoparticles. Campus Kumaun University, Almora 263601, India . DKMT Conference on Integrative Medicine, Nutrition and Health. Scanning electron microscope was used to decide size, location and shape of the Zinc oxide nanoparticles. And they found length and average outer diameter of the ZnO nanotubes were about 2.4 m and 200 nm, respec-tively [43]. The zinc oxide nanoparticles (ZnO NPs) green synthesis were prepared by using Olea europaea leaves extract as bio-reductant agent. Co-precipitation method of synthesis and characterization of iron oxide nanoparticles N D Kandpal*, N Sah, R Loshali, R Joshi and J Prasad. pared zinc oxide nanotubes by hydrothermal syn-thesis using zinc nitrate as a precursor. 8 2.10. Uncoated Zincoxide 42 . Zinc oxide: Healthy or risky 43 2.11. PREPARATION OF ZINC OXIDE NANO- AND MICRO-STRUCTURES USING HYDROTHERMAL-TEMPLATE METHOD AND THEIR APPLICATIONS . of zinc oxide nanoparticle on biodistribution and zinc metabolism in mice over 3 to 35 weeks. Thesis Submitted to the School of Graduate Studies, Universiti Putra Malaysia, in Fulfillment of the Requirements for the Degree of Master of Science . The effects of H 2 S concentration (80-1700 mg L-1), nanoparticle size (18, 80-200 nm), gas flow rate (200 and 450 mL min-1), temperature (1-41 C) and adsorbent … Iron oxide nanoparticles in bacterial cells, Vezér T. in vitro mutagenicity evaluation of iron oxides by!
