Resumen:
Synthetic cytocompatible CeO2 nanoparticles embedded in transparent silica hydrogels are useful for creating inorganic supports favoring the long-term entrapment of living Chlorella vulgaris cells. The key protective role of nanoparticles is twofold: (1) They efficiently absorb harmful UV radiation without scattering the useful visible one. (2) They limit oxidative stress damage, such as that induced by H2O2, thanks to the surface redox Ce3+-Ce4+ reactivity of nanoparticles.
