In the area of biomaterials, students receive an in-depth introduction to the subject via our graduate course, ME681 Biomaterials. Research in this area has branched from faculty expertise in tissue mechanics, powder materials processing, and microfabrication.

Characterizing the material properties of cardiovascular tissues such as heart valves, and how they may be emulated by chemically-treated animal tissue or synthetic materials has been a longstanding interest. In addition, some applied problems related to the manufacturing of functionally structured porous materials for bio-implants are considered in the framework of the general powder science and technology direction. Examples of such material systems include knee implants and dental implant prototypes. These prototype materials have undergone preliminary biocompatibility testing, which allows for rapid feedback on whether further development is warranted. This research has been the subject of several MS theses in the Department.

Biological materials may be grown in vitro, which requires an understanding of how environmental cues influence the tissue growth. Mechanobiology combines mechanical stimulation and tissue culture for investigating the response of valve tissue cells to changes in their environment. Efforts are underway to develop a 3-D printer, a bioreactor and stretching system and to develop the capability to perform fluorescent staining and imaging, in order to build cardiovascular constructs following the principles of tissue engineering. As mentioned earlier in the section on Micro-Electro-Mechanical Systems (MEMS), there are also long-terms plans for advancing our knowledge in large-scale bio-nanoelectronics.
