摘要：
A competitive coordination-based hydrogen peroxide (H2O2) nanosensor is constructed by the assembly of FAM-tagged single-strand (ss) DNA on cerium oxide nanowires (CeO2 NWs). This fluorescent nanosensor is capable of rapidly and selectively tracking H2O2 within living cells, as well as directly visualizing H2O2 generated by wound-induced oxidative damage in zebrafish larvae.
