The photodestruction of virus in Nano-TiO₂ suspension

Abstract

Hepatitis B surface antigen (HBsAg) was selected as reference to evaluate the photodestructive effect of a self-prepared nano-TiO₂ on viruses in aqueous suspension through sandwich ELISA assay (an in vitro enzyme immunoassay) under different conditions, and more general experiments on RNA (ribonucleic acid) and casein were carried out. Results indicate that TiO₂ is destructive at least to most viruses in water. The mechanism of destruction was discussed.
