Abstract Scope |
Two types of TiO2 nanowire architectures were synthesized and their biomedical applications were discussed: TiO2 nanowire fibers of several µm in diameter, and TiO2 nanowire microspheres of several 100 µm in diameter. The fibers and microspheres were derived from in situ alkali hydrothermal treatment of electrospun TiO2 nanofibers and micro-spherical assemblies of TiO2 nanoparticles. Both types of materials were well biocompatible. The fibers showed adsorption and release profiles of drugs and could be utilized as a drug delivery system. The microspheres exhibited good cell attachment and proliferation and could be utilized as a biocompatible cell carrier. |
