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.
