Together with the scientists from The Ohio State University OSU, cell biology researchers at Tampere University have developed a force sensor that can be attached to the side of a mechanically responding protein, allowing it to sense forces and strain on the protein within the cell."The power-sensing part is like athat changes color when stretched. This part is attached to the antibodies at both ends of the rubber band, which bind to the cellular target protein under study.
According to Ihalainen, the force sensor, which is only about twenty nanometers in size, can be easily generalized to a wide range of cell biology research and various target proteins. With the help of thebiosensor, forces can be measured, for example, in the nuclear membrane, between different proteins, or generally in the cytoskeleton of the cell. It allows the mechanics of the cell to be transformed into visible form for the first time.
There has already been great interest in this technology in various laboratories in Japan, India, Norway and the United States.Cells are subject to forces all the time, both in normal bodily functions and diseases. As a cancer cell grows and moves, for example, the cells are subjected to mechanical forces. As the cancer spreads e.g., when it enters blood or lymphatic vessels, the cancer cell has to squeeze through narrow gaps in its microenvironment. Thus,
