Title: Phototriggered Production of Reactive Oxygen Species by TIO2 Nanospheres and Rods
Date: 9/2012
  Link to Journal Abstract
Abstract: We present the study of reactive oxygen species production under the light irradiation of two different types of TiO2 nanocrystals. Both TiO2 spheric NPs and anisotropic nanorods were investigated using activation of the horseradish peroxidase enzyme and subsequent substrate oxidation into a fluorescent product. The influence of the surface ligand dopamine was also explored to shed more light on the effect of catechol binders on the photoactivity of TiO2 species.
Non-technical Summary: In this study, reactive oxygen species production was investigated under the light irradiation of two different types of TiO2 nanocrystals. Both TiO2 spheric NPs and anisotropic nanorods were investigated using activation of the horseradish peroxidase enzyme and subsequent substrate oxidation into a fluorescent product.
