TiO2 is a well-known material and has remarkable physical, chemical and biocompatible properties which have made it a suitable material in the biological world. The development of new TiO2-based materials is strongly required to achieve desired properties and applications. A large number of TiO2 composites have been synthesized and applied in various fields. The present review reports the utility of TiO2 and its composites in biosensing, in Photodynamic Therapy, as an antimicrobial agent and as a nanodrug carrier. The aim of this review is to discuss the biological application of the TiO2 based materials and some recent advancement in TiO2 to enhance its application in the biological world.
Keywords: Antimicrobial; Biocompatibility; Biosensing; Composites; Nanodrug carrier.
