WebMar 9, 2024 · The ‘optical tweezers’, or ‘optical trap’, use the effect by which a laser beam, when focused by the strong objective lens of a microscope, traps microscopic objects. This trapping effect works by exploiting the fact that photons carry momentum and therefore exert minute forces on particles. WebOptical tweezers play an important role in numerous biological studies. Now that the trap strength of our optical tweezers is known, it would be interesting to work with some applications such as measuring the force of different molecular motors. To do this, one would need to attach a molecular motor (I.E. a single-celled organism) to a ...
