The pathological context of liver fibrosis involves excessive ROS production, prompting the need for ROS elimination in fibrosis treatment.[24] Pt‐based nanoparticles commonly exhibit nanozyme activity in addition to their photothermal conversion properties.[25] Herein, the SOD‐like property of PtNZs was evaluated by monitoring •O2− depletion, using a blue chloride (NBT) method at different PtNZ concentrations (Figure 3f). Here, SOD1 is linked to Hepatic fibrosis.
