Electrochemical sensing DNA damage with nano-titanium dioxide and repair with a medicinal herb species resveratrol

We have developed a simple electrochemical method to detect DNA damage caused by the photovoltaic effect of nano-TiO2. Meanwhile, we have found that resveratrol, a Chinese Traditional Medicinal Herb species, can have a repairing effect to the oxidized DNA, which can also be detected with the proposed technique in this paper.
