摘要： A fluorescent probe 4-amino-7-nitrobenz-2-oxa-1,3-diazole NBD-NH2 for critical sensing hypochlorous (ClO-) has been developed in this paper. Probe NBD-NH2 exhibited excellent sensitivity and high selectivity toward detection of ClO- in CH3CH2OH/HEPES solution (1:4, v/v, 10 mM, pH 7.4), where the detection limit as low as 40 nM. The green fluorescence of NBD-NH2 was distinctly quenched by addition of ClO-. In addition, the new probe was also applied for bioimaging using HeLa cells and exist a critical detection of ClO- in living cells. [GRAPHICS] .
