Fig. 1 (A) Fluorescence spectra of the probe (5 μM) with different concentrations of H2O2 for 30 min in PBS buffer at 25 °C (pH 7.4, containing 50% ethanol, v/v); (B) linear relationship between fluorescence intensity ratio and H2O2 concentration. Slit widths: 5/5 nm. λex = 300 nm, λem = 366 nm/450 nm.
