摘要：

Nucleic acid-based probes have been widely exploited for biosensing by virtue of their excellent physicochemical and ease synthesis properties. Given that the aggregation-induced emission, and hydrogen peroxide (H2O2) can be converted hydroxyl radical (·OH) to cleave nucleic acids, a new nucleic acid-based probe has been developed for H2O2 assay. Herein, a novel carbazole derivative of 3-(3-(2-(1-ethylquinolin-1-ium-4-yl)vinyl)-9H-carbazol-9-yl)propanoate (EVCP) was designed with enhanced fluorescence signal by G-quadruplex labeled with FAM (G...
