Optical tweezers

Optical tweezers are scientific instruments that use a highly focused laser beam to provide an attractive or repulsive force depending on the refractive index .

The radiation pressure from a focused laser beam is able to trap small . Har du nogensinde forestillet dig, at du kan bruge lys til at flytte en mikroskopisk plast-perle? Udforsk kræfter på perlen lad tiden gå langsommere . The Optical Tweezers Group at the Niels Bohr Institute at the University of Copenhagen work at the cross roads of physics, optics, biophotonics, .

Today: Widely used tool in physics, chemistry biology. The group started out being centered around the possibilities offered by high quality optical tweezers platforms, however, our equipment park now also offers . Optical tweezers were first realized years ago by Arthur Ashkin and. Our modular optical tweezers have the flexibility required for experiments conducted in advanced research laboratories.
