TOMSK, Jan 10 – RIA Tomsk. Researchers of Tomsk Polytechnic University (TPU) created a line of nanostructural coverings for the titanic implants applied in traumatology which will allow "to disguise" an implant for its best implantability after a surgery, the press service of TPU reports on Wednesday.
Earlier it was reported that TPU scientists develop nanocoverings for titanic implants, which can be "impregnated" with drugs. They consist of the nanotubes (hollow cylinders from titanium dioxide) interfering destruction of a bone tissue which can begin because of features of distribution of loading between a bone and implants. And if to apply a covering from hydroxyapatite on nanotubes, then it "will disguise" titanium, and the artificial limb will get accustomed.
It is noted that hydroxyapatite is the main mineral component of bones and teeth. Also the scientists developed a covering from calcium-phosphate which improves survival of bone implants: calcium and phosphorus which are its part – a basis of an inorganic phase of a bone tissue.

"The graduate student of TPU Roman Chernozem is the first in Russia who managed to repeat an experiment of the British colleagues and to apply … a covering from hydroxyapatite on nanotubes. Besides, having conducted a research, the TPU scientists and their colleagues established for the first time that coverings on the basis of hydroxyapatite are formed on nanotubes with a smaller diameter (less than 100 nanometers) and if to increase their diameter, calcium-phosphatic covering is formed", – it is said in the statement.
It is explained that this opening will allow to apply nanotubes to delivery of drugs in patients' organisms together with implants in the future.
"In the long term this technology will allow to approach more personified treatment and rehabilitations of each patient, selecting that type of nanotubes for implants which is necessary in each case", – the press service quotes the head of the Center of TPU technologies Roman Surmenev.
