The biomedical research effort within the Department of Materials Science and Engineering is dedicated to the understanding of interactions of inorganic and organic materials, ranging from single molecules to full scale implants, with biological systems, in particular the human body. We are interested in the interfacial and biological phenomena that are governed by material and medicinal chemistry, electrochemistry, and metallurgy. Our mission is to provide education and research opportunities for undergraduate and graduate students in biomedical materials science, and to establish strong national and international networks.
The name biomedical materials science has been selected to specify our interest in incorporating any material type (metals, ceramics, polymers, composites, and organic molecules) into biomedical applications and medicines. Our motivation is to contribute to improved patient treatment and care, safety, quality of life, as well as design of biocompatible structures which are durable in a biological environment. Results are obtained by evaluation of the material/molecular – fluid – biological system interactions and the host system response, which is further used as decisional basis for medical device material and medicinal design, improved performance, as well as for appropriate risk management.
The Synergy Group – Biomedical Materials Science is an interdisciplinary team working together to holistically address and shape the future of biomedical applications and medicines.

What is Biomedical Materials Science?
The study of the material and biological interactions that substantially govern the outcome of a biomedical devices has traditionally been known as the field of "biomaterials." In recent years, however, the term "biomaterials" has also been used to describe the study of other applications such as cellulose, silk, coral, etc. The name "biomedical materials science" has therefore been selected to specify the groups interest in the study of biomedical materials for implant/prothesis/device applications, as well as small bioactive molecules as drugs and drug systems.
