Optical Force Measurements

Optical tweezers are a tool that can be used for trapping and manipulation of small transparent objects, such as cells and bacteria. This is possible since light carries momentum and thus can exert forces, or radiation pressure, on matter.

After calibration of the force exerted by the trap at known experimental conditions, the optical tweezers can also be used as a tool to measure or exert precise forces in the order of pN.

We build optical tweezers setups for force measurements and external stimulus of cell membranes with probe particles, in order to investigate membrane stiffness and intra- and intercellular signaling. Studies are currently performed of both yeast and mammalian cells.
