The micelles (CPMs) have a thermoresponsive surface and reactive oxygen species (ROS) generating core. At 37 °C, CPMs captured Aβ aggregates to inhibit and disaggregate aggregates under white-light irradiation, reducing Aβ-induced cytotoxicity.

An in situ photo-Fenton-like and magnetic recycle system, BaFe12O19/Ag3PO4 has been constructed. BaFe12O19 can catalyze the conversion of H2O2 to generate ROSs (˙O2− and ˙OH radicals) on the surface of Ag3PO4.

Nitric oxide (NO) and reactive oxygen species originated from [Ru(pc)(pz)2{Ru(bpy)2(NO)}2](PF6)6(I) have been postulated to act synergistically against cancer cells. NO is released from (I) by the reduction process and singlet oxygen formation by light irradiation at 660 nm.
