Abstract:

Riga Biomaterials Innovation and Development centre (RBIDC) is the biggest and most modern biomaterial research center in the Baltic states. The main research fields are medical implants, tissue engineering and ecomaterials.
Wet precipitation method is used to obtain different calcium phosphates for production of medical devices. The parameters such as raw materials, process temperature, suspension pH values, dosing rate of reactant, stirring speed, concentrations, etc. strongly affect the properties of final product. Evolving the optimal conditions it is possible to obtain desirable phase composition of product (powder form). The chemical and physical properties of the powder or ceramics are determined by Fourier transform infrared spectroscopy, X-ray diffractometry, scanning electron microscopy, differential thermal analysis, optical dilatometry, optical microscopy etc. Obtained calcium phosphates are used for production of hydroxyapatite ceramics with adjustable degree of biological activity and porosity, glass ceramics and composites, scaffolds for medicine immobilization inside of materials (drug delivery systems). Innovative direction is biofunctionalization of material structure and surface. RBIDC collaborates with doctors from Riga Stradins University to find out and understand specific features which could be useful for manufacturing implants thereby enhance treatment of patients.
