How does a somatic cell react to a certain medication? How do tumour cells move? To develop new therapies for widespread diseases such as cancer and Alzheimer's, it is indispensable to create cell cultures. The patented plastic carriers of the biotech company Ibidi offer optimum growth conditions. Their surfaces simulate the structures of an organ with the help of a tiny relief on the nanometre level. The translucent cell biochips were developed jointly by physicists, chemists, biologists, and engineers and are excellently suited to high-resolution microscopic studies.
