Optical Stretcher for Adherent Cells — •Alexander Janik, Tobias Neckernuß, and Othmar Marti — Institute of Experimental Physics, Ulm University

We have demonstrated a method to stretch adherent cells with a parallel laser beam, that is capable of distinguishing between stiff and softened cells. Recently, a new method for the detection of the membrane displacement was developed. It relies on off-axis interferometry, which allows for high precision as well as arbitrary positioning of the probed spot and makes the method completely contact-free.
