Journal ArticleDOI
Zinc oxide nanoparticles for selective destruction of tumor cells and potential for drug delivery applications.
TL;DR: Through a better understanding of the mechanisms of action and cellular consequences resulting from nanoparticles interactions with cells, the inherent toxicity and selectivity of ZnO nanoparticles against cancer may be improved further to make them attractive new anticancer agents.
Journal ArticleDOI
Cytotoxicity of ZnO Nanoparticles Can Be Tailored by Modifying Their Surface Structure: A Green Chemistry Approach for Safer Nanomaterials.
Alex Punnoose,Kelsey Dodge,John W. Rasmussen,Jordan Chess,Denise Wingett,Catherine B. Anders +5 more
TL;DR: It is demonstrated that by modifying the synthesis parameters/conditions and the surface chemical structures of the nanocrystals, their surface charge density, catalytic activity, and cytotoxicity can be tailored, which provides a green chemistry approach to produce safer ZnO NP.
Journal ArticleDOI
Improving the selective cancer killing ability of ZnO nanoparticles using Fe doping.
Aaron Thurber,Denise Wingett,John W. Rasmussen,Janet Layne,Lydia M. Johnson,Dmitri A. Tenne,Jianhui Zhang,Charles B. Hanna,Alex Punnoose +8 more
TL;DR: The non-immortalized human T cells are markedly more resistant to Fe-doped ZnO NPs than cancerous T cells, confirming that Fe- doped samples still maintain selective toxicity to cancer cells.
Journal ArticleDOI
Enhanced Dye Fluorescence in Novel Dye–ZnO Nanocomposites
Jianhui Zhang,Aaron Thurber,Dmitri A. Tenne,John W. Rasmussen,Denise Wingett,Charles B. Hanna,Alex Punnoose +6 more
TL;DR: In this paper, a new fluorescein isothiocyanate/fluoressein/rhodamine B-doped ZnO composite nanostructures including tripods, tubes, and rods with tuned sizes have been designed and synthesized to greatly enhance the dye fluorescence up to ∼90 fold.
