A novel fluorescent probe based on ESIPT and AIE processes for the detection of hydrogen peroxide and glucose and its application in nasopharyngeal carcinoma imaging

A novel fluorescent probe HPQB based on ESIPT and AIE was developed for the detection of H2O2 and glucose. HPQB was found with large Stokes shift (167 nm) characters. Probe HPQB exhibited high selectivity and excellent sensitivity for H2O2 and glucose. Moreover, HPQB was also employed as a fluorescent probe for imaging H2O2 in nasopharyngeal carcinoma (NPC) cells.
