TOMSK, Feb 13 – RIA Tomsk, Karina Sapunova. Scientists of Tomsk Polytechnic University (TPU) develop nano-coating for titanic implants which can be "impregnated" with the drugs which are specially chosen for the specific patient; "capacity" of the Tomsk coating will be more, than at analogs, the chief of TPU Center of technologies Roman Surmenev reported RIA Tomsk on Monday.
"Nanotubes from which, as from honeycombs, consists the covering, is hollow on the structure, and it is possible to load it with various medicines, biomolecules and other: it may be, for example, something stimulating an osteosynthesis and survival of an implant or antibacterial additives. It is possible to load into one cell even a set of substances – for example, antibacterial means will be released at first, and then – medicine", – he told.
According to the interlocutor of the agency, it will allow to pick up and enter into an organism of the patient drugs which will help him individually.
Surmenev added that similar developments in the world are conducted, but so far any of materials isn't introduced in clinical practice. In Tomsk "nanocontainers" it is possible to place more substances, than in analogs. Diameter of tubes – up to 100 nanometers, and length – up to several micrometers. Now polytechnicians conduct basic researches, made prototypes of nano-coatings and look for partners for development of the project.As it is specified on the website of TPU, nanotubes from titan dioxide also interfere with destruction of a bone tissue which can begin because of features of distribution of loading between the bone and implants which are traditionally made of the titan. And if to apply a covering from a hydroxyapatite on nanotubes, it will "disguise" titanium and the titanium prosthesis will quicker get accustomed.
According to the university, scientists from several divisions of TPU together with colleagues from University of Duisburg-Essen and Karlsruhe Institute of Technology (Germany), University of California, Riverside (USA) and others work on the project.
