WebAug 20, 2002 · Optical tweezers were invented in the mid-1980s by Arthur Ashkin and co-workers at the Bell Telephone Laboratories. Since then there has been a steady stream of developments and applications,... WebOptical tweezers is a Nobel-prize winning technology and enables the quantification of molecular, cellular and micro-rheological processes. Applications include molecular motor mechanics, binding/elasticity of DNA and proteins, cell membrane dynamics and particle uptake into cells.

WebOptical tweezer toolbox. (a) An RNA polymerase enzyme (green) synthesizes a strand of RNA (orange) from DNA. The enzyme is fixed to a micron-sized polystyrene sphere. Optical tweezers (pink) hold the sphere with a force of known magnitude. The force exerted by the enzyme’s movement can be measured as the enzyme transcribes the genetic material.
