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.
