ansported away from the cells when a liquid flows by," explains Dr. Raimund Jaeger, group manager at the IWM. "Understanding these processes can be helpful for cell culture." To produce the model, the research scientists initially studied the mechanical properties of the individual polymer fibers and for this purpose developed a special apparatus. On a silicon chip measuring one square centimeter, the scientists in Halle etched approximately 50 "microtesting machines". They then placed and fastened the fibers over the testing machines. Under the microscope the researchers were able to observe how the fibers behave when they are pulled, how far they stretch and when they snap. As fiber-like structures are frequently encountered in nature and technology, suitable experimental techniques and simulation methods have a wide range of applications.
