CeO 2 nanoparticles for the protection of photosynthetic organisms immobilized in silica gels
Synthetic cytocompatible CeO 2 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...
