Recently, scholars from the Nuclear Technology Engineering School and the New Production Technology Engineering School of the Tomsk University of Technology in Russia, together with foreign experts in the field of medical materials, have developed a method for synthesizing nanotubes using titanium dioxide. This catheter is coated with a calcium phosphate coating. The composition of the coating is the same as that of human bone, which is equivalent to covering the titanium graft with periosteum, which can improve the survival rate of the titanium bone graft.
The researchers pointed out that at present, titanium is widely used in the production of implants, but the elasticity of the two is different. Titanium is much harder than bone tissue. Therefore, when the patient moves, titanium bears more mechanical load than bone, which may cause bone tissue damage. Graduate student Roman Chernozem said: "Nanotubes help to solve this problem and avoid letting titanium bear more mechanical load than bone tissue."
In addition, the hollow nanocatheter is also very suitable for being filled with drugs and delivered to the required parts of the body together with the graft, and the drug delivery speed can be controlled.
