Fig. 3. In vitro photocleavage of P407-CM-T.

a Liquid chromatography curves of tetracaine (black line), P407-CM-T before (brown line) and after cleavage (blue line) under 400 nm LED irradiation. b Mass spectrum corresponding to the peak at 5 min in the curve of P407-CM-T + light in a. c Photocleavage of P407-CM-T solution (10 mg mL⁻¹) over time under 400 nm LED at different irradiances (n = 4, Data are means ± SD) (black line: 25 mW cm⁻²; red line: 50 mW cm⁻²; blue line: 300 mW cm⁻²).
