Resumen:
Synthetic cytocompatible CeO2 nanoparticles embedded in transparent silicahydrogels are useful for creating inorganic supports favoring the long-term entrapment of livingChlorella vulgaris cells. The key protective role of nanoparticles is twofold: (1) They efficientlyabsorb harmful UV radiation without scattering the useful visible one. (2) They limit oxidativestress damage, such as that induced byH2O2, thanks to the surface redox Ce3þ-Ce4þ reactivity ofnanoparticles.
