Optical Tweezers can be used for studying mechanical properties of molecules, soft matter, tissues or cells. Optical tweezers make use of highly focused laser beams that can trap and manipulate microscopic particles, such as beads, liquid condensates, colloids and soft matter physics characterization, biological tissues & cells and even molecules.

Optical tweezers operate based on the principles of light momentum transfer. When a laser beam is focused through a high numerical aperture (NA) lens, it creates a strong electric field gradient. This gradient exerts a force on dielectric particles, drawing them towards the region of highest intensity, typically the focal point of the laser beam.This technique can be applied to perform rheology  fields, particularly biology, material science and (soft-matter) physics.
