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, biological 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 reology  fields, particularly biology and physics.

The Impetux Optical Trap is available on the Nikon X-light V3-01 Spinning disk and needs to booked as an alias in PPMS
