An Ag–TiO2–reduced graphene oxide hybrid film for electrochemical detection of 8-hydroxy-2′-deoxyguanosine as an oxidative DNA damage biomarker

Abstract

Here, a notably sensitive and selective electrochemical sensor based on an Ag–TiO2–rGO hybrid nanomaterial modified SPE was developed for 8-OHdG detection, which is a significant DNA biomarker due to one of the main products of oxidative DNA damage.
