Nanocrystalline Titanium Dioxide for Disinfection and Sterilization

Nanocrystalline Titanium Dioxide for Disinfection and Sterilization


Titanium dioxide based materials are commonly known as Photo-catalysts of environmental and biomedical relevance. Photoactive TiO2 irradiated with ultraviolet light shows antiseptic, fungicidal, disinfecting and odor-neutralizing properties. It can be used for production of self-cleaning surfaces as well as disinfection, sterilization or odor-neutralizing agents.

The subject of this offer includes photocatalytic materials produced by a smart modification of nanocrystalline titanium dioxide. The new materials absorb visible light that initiates the photocatalytic processes. Under these conditions photodegradation of organic compounds and bacteria inactivation proceed very efficiently.

The main advantages of modified nanocrystalline titanium dioxide are:

• lack of the dark-toxicity of both the modified material and its components;

• visible light induced strong effect of phototoxicity towards microorganisms allowing elimination of expensive and harmful ultraviolet light sources; formation of transparent colloidal solutions that can be easily applied for various surfaces impregnation and coating thus forming thin photocatalytic layers;

• stability in a wide range of pH, especially in the neutral conditions (pH=7), contrary to unmodified TiO2 stable in the form of transparent colloids only in acidic media;

• lack of any negative influence either on natural environment or human body;

• low production costs.
