Scientists of Far Eastern Federal University (FEFU) created an innovative technology of synthesis of advanced biomaterials for regenerative bone surgery. New ceramic biomaterial has a high porosity and strength that will ensure a more effective integration of an implant in the skeleton. The results of such approach have been published in an authoritative Royal Society of Chemistry international scientific journal.

As explained by the major contributor to the research, Oleg Shichalin, graduate student, Department of Materials Science, FEFU School of Engineering, in medicine there is an acute problem of improving medical materials for human bone tissue regeneration. One of the most important properties of bioceramics, used as implants, is a well-developed porous structure of high structural strength. It provides an effective osteointegration (bone germination depth into implant) and reduces the likelihood of excessive bone destruction. Compliance with such conditions is extremely challenging for the traditional methods of synthesis, which require advanced and innovative approaches.

FEFU researchers offer a new method for the synthesis of porous ceramics based on synthetic wollastonite (class of silicates) and special material connection technology. The uniqueness of the approach is to use two types of pore-forming additives to be incorporated at different stages of the combined synthesis of the material. This ensures the formation of porous silica frame with a high structural strength, and the additional components added into the composition make it compatible with a bioorganic medium.

Such high-tech approach allows one to create new and previously unexplored bioactive ceramic materials. These are artificial bone matrices with the structure and properties similar to bone tissue. The resulting material is of a modern bioceramics class and meets all necessary requirements of modern medicine.

The development of the new ceramic material is carried out in the Laboratory of Nuclear Technology, School of Natural Sciences, under the guidance of Eugene Papynov, FEFU Research Fellow. The research is conducted out with the support of the Department of Materials Science (headed by Julbarshon Mansurov), Laboratory of Mechanical Testing and Structural Analysis of Materials Common Use Center (headed by Ekaterina Gridasova), School of Engineering, as well as in close collaboration with the Institute of Chemistry of the Far Eastern Branch of the Russian Academy of Sciences.
