Characterization of Cr(v)-induced genotoxicity using CdTe nanocrystals as fluorescent probes

Abstract

CdTe nanocrystals capped by cysteamine were synthesized to study Cr(V)-induced genotoxicity. On the surface of TiO₂ thin films, the stepwise process of DNA breakage induced by Cr(V)–GSH complexes was vividly observed by using CdTe–DNA self-assembled fluorescent probes; in acetate buffer solution, an analytical method was developed to detect Cr(V)-induced genotoxicity with CdTe fluorescent probes.
