The Physics and Biology
of a Biomaterials Sensor


Biofilm formation is an important aspect in, e.g., the development of biomaterials or anti-fouling materials. These all have surfaces which are in contact with blood, sea water or other biological systems. This seminar is about the physical principles behind a very sensitive sensor to measure and monitor the formation of thin films on solid surfaces in liquids. A recent development of the quartz crystal microbalance (QCM) technology allows quantitative and qualitative analysis of an adhesion process in real-time. About half of the seminar will be dedicated to accessible examples in areas such as protein adsorption, lipid layer and bilayer formation, enzymatic degradation, immune complement activation , bacterial film formation and cell adhesion.

Please join us for light refreshments at 4:15pm outside WSC 109.
