Biomedical techniques

Our research on biomedical technology relates to the development and application of new concepts, methods and techniques to solve diagnostic and treatment problems in medicine. Our research interests are wide-ranging with a recent focus on following topics

  1. Micro and nanoscale surface modification of biomaterials and their applications in medical implants, electrodes and biosensors
  2. Development of wearable sensors and systems for physiological measurements
  3. Development of novel spectroscopic methods for biomedical applications such as cancer diagnostics
  4. Implants and novel biomaterials

Research on implants and biomaterials is focused to bone cements, bone screw fixations and hip implants.  Biocompatibility, wear, corrosion, biomechanical properties etc. are tested and simulated using experimental models and testing techniques as well as by computer simulation. For example, new coating materials, such as amorphous diamond, carbon nitride or Ti-based coatings, are developed to reduce wear and improve biocompatibility of the fixation devices or joint implants. Furthermore, we utilize our deposition techniques in the research and development of novel biosensors.

Due to the extreme multidisciplinary nature of our research, a large collaboration network including clinical experts and companies is vital for enabling to reach the ambitious goals set for projects. We actively collaborate with several national and international research institutions, hospitals and industrial partners.

Here are some examples of our current projects:

  • cell attachment and proliferation studies on thin film textures surfaces
  • textured conductive polymer electrodes (pillars)
  • electrode set for bruxism
  • spectroscopic diagnostics with saliva
  • bone cement enhanced screw fixations in osteoporotic bone
  • matrix biosensors for humans and animals
