Websample, are often used in optical tweezers instruments. These can have numerical apertures of up to 1.4. The use of high power lasers also maximizes the trapping force. An alternative optical tweezers design that can easily overcome the loss due to reflection at the bead surface uses a dual-beam design, shown in Figure 4. 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 ...
