a H&E (Scale bar: the top of 100 µm and the bottom of 25 µm), and b Masson staining of wound tissues treated with Control, Control + NIR, CeO2 + F− + TMB, and CeO2 + F− + TMB + NIR (Scale bar: the top of 100 µm and the bottom of 25 µm). Concentration: CeO2 (30 µg/mL), F− (400 µM), TMB (1 mM), acetate buffer (pH 4, 20 mM). c Quantification of collagen volume fraction. d Levels of IL-1β and IL-6 (pg/mg), e IL-10 and VEGF (pg/mg). Error bars represent the standard deviation from the mean (n = 3)
