Doctor's thesis of Philosophy: An investigation of the in vitro toxicity of zinc oxide nanoparticles in UV-irradiated skin cells

This study investigated the in vitro effects of ZnO NP and chemical UV filters commonly used sunscreens on the function of immortalised and primary skin cells. ZnO particulates (30 nm, 80 nm and 200 nm) were compared to the chemical UV filters: butylmethoxydibenzoylmethane (BMDBM) ethylhexylmethoxycinnamate (EHMC), ethylhexylsalicylate (EHS), homomenthylsalicylate (HMS) and 4-methylbenzylidenecamphor (MBC). Human epidermal keratinocytes (NHEK), epidermal melanocytes (NHEM), dermal fibroblasts (NHDF) and the immortalised keratinocyte HaCaT cell line were used in this study.

Báo cáo khoa học: The effect of zinc oxide nanoparticles on the structure of the periplasmic domain of the Vibrio cholerae ToxR protein

Proteins adsorbed on nanoparticles (NPs) are being used as biosensors and in drug delivery. However, our understanding of the effect of NPs on the structure of proteins is still in a nascent state. In this work we report the unfolding behavior of the periplasmic domain of the ToxR protein (ToxRp) of Vibrio choleraeon zinc oxide (ZnO) nanoparticles with a diam-eter of 2.5 nm.
