BBCE coordinating institution - Riga Technical University (RTU) is one of the oldest institutions of higher technical education in Eastern Europe. RTU gathers more than 16000 students, staff of 611 people for research and 572 for teaching, currently is the top 1 University in Latvia in terms of scientific potential and it is ranked among the top 651–700 Universities worldwide. Rudolfs Cimdins Riga Biomaterials Innovation and Development Centre of RTU (RTU RBIDC) is the biggest and the most modern biomaterial research centre in the Baltic States. RTU RBIDC research team consists of 30 scientists with background in chemistry, chemical engineering and materials science. The main areas of RTU RBIDC research activities include training and research on synthesis of calcium phosphates, preparation of inorganic/organic composite materials, bone cements, and upscaling of chemical engineering processes for bone regeneration purposes. Additional research fields include drug/ion delivery systems and nanostructured implant composites with drug eluting properties. The biomaterials developed at RTU RBIDC have been tested in clinical practice for more than 15 years in more than 400 patient cases.
