Myocardial ischemia is a pathological condition where cardiomyocytes lack oxygen and energy supply. Here, Cheng et al. develop a photosynthetic system consisting of Chlorella pyrenoidosa (C. pyre) and upconversion nanoparticles encapsulated in a hydrogel, which upon exposure to near-infrared light, enables oxygen production by C. pyre to alleviate the hypoxic myocardial environment.
