The Optical Stretcher


The Optical Stretcher is a tool for cell analysis. It measures the deformation of cells that is caused contact-free by optical forces.

The measured biomechanical properties give insight to the cellular structure, internal processes and to changes caused by external cues. Since the method also allows to detect fluorescent signals it is possible to correlate the mechanical information to the underlying molecular processes.

The Optical Stretcher can be applied in the field of cancer research, for basic research but also for drug screening purposes and diagnostic approaches. Further applications are stem cell research, biophysical research, investigation of immune responses of cells.
