1 BioMater Centre - the equipment and services at the university - Virpi Tiitu Translational research-kuh and UEF opportunities

2 Basic Role of BioMater Centre "BioMater Centre acts as an independent department to provide services and equipment for researchers in different faculties." Operational focus areas in the Centre: to develop methods and modernize the equipment for biomaterials research to develop and activate education, instrumentation and research for the specific fields of research to utilize the equipment and know-how for the industrial needs One of the goals is to support development of education and research of technical and natural sciences

3 Status of BioMater in UEF Supports many of the strong research areas in UEF: Molecular medicine, drug development, biotechnology Environmental health and climate change Optics and new materials Forestry and environment BioMater acts as an interface to local high tech companies (analytical services, etc.) national companies and research centers and even to international companies and research networks in demanding projects

4 BioMater Centre in the University of Eastern Finland The goverment of the University of Eastern Finland Rector, academic rector Philosophical Faculty Faculty of Science and Forestry Faculty of Health Sciences Faculty of Social Sciences and Business studies BioMater - SMARC - InFotonics SIB-labs 2011

5 Laboratories in the BioMater Material testing: Centre Instron, Lloyd, hip joint simulator (destructive) Impedance, roughness, etc. (non-destructive) Microscopy: Optical microscopy (incl. confocal microscopy) Electron microscopy (TEM, SEM) Spectroscopy (FTIRi, FTIR, Raman) Sample preparation (EM samples, hard tissues) (Bio)chemistry Structural analysis: microct, ultrasound
