Rapid-Response and Highly Sensitive Boronate Derivative-Based Fluorescence Probe for Detecting H2O2 in Living Cells
Fluorescence emission spectra of TPIOP boronate after reacting with (a) 15 μM H2O2 and 15 mM of other ROS and (b) 15 μM H2O2 along with 15 mM of other ROS. (c) Bar chart of selectivity and interferences of TPIOP boronate. Experimental conditions: 2 μM of TPIOP boronate in 10 mM HEPES buffer solution (pH 7.4 and 2 vol% DMSO). (1) TPIOP probe, (2) H2O2, (3) KO2, (4) , (5) TBHP, (6) mCPBA, (7) HOCl, (8) , (9) , (10) , (11) ONOO−, and (12) BPO, respectively. Insets: corresponding fluorescence images.
