Figure 2

(a) Fluorescence emission spectra of the probe TPIOP boronate (1) before and (2) after reacting with H2O2 to form TPIOP-OH. (b) Time-dependent fluorescence intensity at 467 nm in 2 μM TPIOP boronate using various concentrations (0 to 15 μM) of H2O2 at 10 mM HEPES buffer solution (pH 7.4 and 2 vol% DMSO).
