Advantages

Oleanolic acid-loaded iron single-atom catalyst embedded in hollow carbon nanospheres and encapsulated by erythrocyte membrane

Fe-SAC catalyzes conversion of endogenous hydrogen peroxide into hydroxyl radicals

Released oleanolic acid enriches cellular membranes with polyunsaturated fatty acids

Achieves lipid peroxidation amplification-enhanced chemodynamic therapy
