Phototriggered Production of Reactive Oxygen Species by TIO2Nanospheres and Rods

Abstract

We present the study of reactive oxygen species production under the light irradiation of two different types of TiO2nanocrystals. Both TiO2spheric 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 TiO2species.
