Description
Summary:The interaction of linear DNA molecules (hydrolysis products of Lambda phage DNA) with nanoscale modifications of titanium dioxide with anatase and η-TiO 2 structures is studied. The photosensitization of adsorption and degradation processes of DNA under the effects of visible light is revealed. It is established that the anatase exhibits increased activity towards DNA in a low salt buffer, while η-TiO 2 has a higher adsorption capacity in a buffer with high ionic strength. Recommendations on the practical application of nanoscale modifications of titanium dioxide with the structures of anatase and η-TiO 2 are given.
