The problem of Transplantology in the last time is particularly acute, and to help people to improve their health and “wait” on the right will help artificial organs. If a bone marrow transplant, liver or kidney, more or less debugged, now to find a donor of bone tissue is problematic. Therefore, the invention is an artificial bone is extremely important.

For new development responsible scientists of chemical faculty of Tomsk state University (TSU). They have patented a method of synthesis of the main mineral component of bone tissue that will bring artificial bone to its natural counterpart that will not cause rejection reactions of the transplant. According to the Professor of inorganic chemistry, Tomsk state University Natalya Korotchenko,

“The main mineral component of bone is hydroxyapatite. He needs high porosity. Our scientists have invented a new method of synthesis of powder in the microwave field with the use of vegetable gelatin agar-agar, which is made from seaweed. Gelatin is burned under high temperatures, after which the material is pores”.

The presence of pores in the newly formed “blank” promotes better germination bone through the implant and increases the biocompatibility of the synthetic material with human tissue.

“Microwave radiation heats quickly and evenly irradiated to the sample, making the process of synthesis of hydroxyapatite requires less time and energy costs.”

In addition, thanks to the introduction of the structure of ions of different metals, scientists were able to modify the hydroxyapatite. For example, the introduction of silver ions enhances the antibacterial properties of the material, and silicate-ion contributes to the improvement of biocompatibility.
