Fig. 5From: 3D printed hydrogel scaffolds combining glutathione depletion-induced ferroptosis and photothermia-augmented chemodynamic therapy for efficiently inhibiting postoperative tumor recurrenceChemodynamic behavior of Gel-SA-CuO hydrogel scaffolds. The absorbance curves (a) and absorption values at 664Â nm (b) of methylene blue mixed with released solution from indicated scaffolds. The influence of reaction time (c and d), reaction temperature (e and f), and power density (g and h) on the degradation of methylene blue. i Schematic illustration of enhanced catalytic activity of Gel-SA-CuO by photothermal effect induced temperature increaseBack to article page
