Fenton’s reagent-induced UPE measured using near-infrared PMT from the porcine skin sample. (A) Kinetics of UPE was measured after the topical application of Fenton’s reagent (100 μM containing 500 μM FeSO4). (B,C) Kinetics of UPE was measured after the topical application of Fenton’s reagent (1 mM H2O2 containing 500 μM FeSO4) added between 30 s and 1 min of the start of measurement (indicated by arrow) in the absence (B) and presence (C) of sodium ascorbate (5 mM), respectively added prior to treatment with Fenton’s reagent. The decay curve was measured for a duration of 10 min.
