Single-molecule Detection of Reactive Oxygen Species: Application to Photocatalytic Reactions

Original Paper

Abstract

In this review, we have focused on the oxidation reactions of single dye molecules by reactive oxygen species (ROS). The methodologies for the single-molecule detection of ROS, such as hydroxyl radical (HO), singlet oxygen (O2(a1Δg)), and hydrogen peroxide (H2O2), have been introduced together with examples. In particular, a successful application using the single-molecule fluorescence technique for the investigation of the TiO2 photocatalytic oxidation reactions is demonstrated in detail.
