A Review on Biomedical Applications of Titanium Dioxide

Abstract

Titanium is a wonder metal with broad range of application in all aspects of life. Applications include aeronautical, industrial, military, automobiles agriculture and in the field of medicine. Titanium dioxide is the most common compound of titanium it occurs commonly in three crystalline forms namely anatase, rutile and brookite. The nano particles of titanium dioxide have low toxicity, versatile fabrication adaptability which forms the basis for its broad range of application. This review article discusses applications of titanium dioxide nanoparticles in cancer therapy, targeted drug delivery, photodynamic therapy, antibacterial effect, role in bone formation and general applications.
