As more and more chemical activity and biological activity are found, cerium, one of the largest reserves of cheap rare earth lanthanides, is widely used in many fields such as flint, decolorizer, abrasive polish, glass additives, reducing agents, catalysts, harmful metal substitutes and other special functional materials. Cerium nanoparticles can be used in cardiovascular diseases, neurodegenerative diseases and radiation-induced tissue damage, also be used as biomimetic enzymes, biocatalysis, biomedicine, biological scaffolding and other biological fields. However, cerium-based hollow nanospheres have never been properly tested as a drug carrier. In this report, we explored the potential of cerium-based materials as a drug carrier which is a brand new attempt to expand the scope of application of cerium-based nanomaterials in the field of biomedicine.
