TiO2 Benefits are many and in this recent article titled “Helicon Healing” ScienceWise magazine explains how Dr Christian Sarra-Bournet, a physicist, explores the possibilities of TiO2 being used for destruction of bacteria in nosocomial infections and coating of implants such as knees and hip replacements. According to Dr.Christian Sarra-Bournet ,“TiO2, is an excellent biocompatible material and possesses bioactive properties”
“Nosocomial Infections are those acquired whilst being treated in hospital(s) for other conditions and are of very serious concern to the medical community. They are one of the major causes of death in hospitals, accounting for almost 100,000 annual fatalities in the USA alone.”
“Titanium Dioxide TiO2 is most well known as the white pigment used in paints, but… TiO2 benefits are not limited to paint alone… ‘it has many other interesting properties. In its crystalline form, TiO2 is a semiconductor that exhibits some extraordinary photocatalytic properties. When ultra violet light shines on a TiO2 crystal, it generates electron-hole pairs, which can migrate to the surface to serve as a source of free electrons and electron absorbers. These form the basis for oxidation and reduction reactions, which can in turn create free radicals which attack the cell wall of bacteria, ultimately killing them. “One of the limitations of TiO2 is that its large band gap requires ultra violet light to generate the electron hole pairs,” So Dr. Christian Sarra-Bournet discovered that” by creating a material with the same antibacterial properties that’s sensitive to visible light, we have something much more practical.”
