Biofluid Mechanics (2007-2011)


The aims of the RG are to gain insight into the onset of calcification of biological and engineered heart valves by testing biological heart valves in an accelerated fatigue testing machine to study the beginning and progress of the calcification. And to develop scaffolds out of biomimetic materials for different applications with the methods of electro-spinning and directional solidification.

Research Focus

The main focus of the research group is to identify influence factors which lead to the calcification of biological heart valve prostheses. A special heart valve calcification tester which allows exposing the prostheses to defined conditions will be at free disposal for these tests. Another focus is to develop scaffolds via electro-spinning from synthetic polymers. Growth factors are introduced into the electrospun fibres. By means of directional solidification sponge like structures can be produced which can be seeded with different cells. Furthermore a dynamic perfusing bioreactor shall be developed to permit scaffolds, whether of natural or synthetic origin, to be seeded in a defined manner with cells.
