A Scheme for nanoceria of self-regulated photodynamic properties at various tissue physiological conditions. B SOSG detects 1O2 production of control, SPN-0, and SPN-C23 under 808 nm laser irradiation. C HRP/Amplex Red detects H2O2 generated at pH = 6.5 or pH = 7.4 under NIR laser irradiation. D Relative tumor growth curves after intravenous injection of saline and varied treatment groups. E H&E staining for evaluated tissues damaged after PDT [31].
