Effect of surface modification on the bioactivity of sol-gel TiO2-based nanomaterials

摘要

BACKGROUNDSurface composition of titanium dioxide (TiO2) nanoparticles strongly affects their biocompatibility and cytotoxicity. The appropriated functionalization of TiO2 nanoparticles leads to the improvement of these properties; while increasing biocompatibility allows the safety use of TiO2 nanoparticles, their cytotoxicity can be properly used in cancer therapy.
