MIT researchers have developed a novel technique to measure the strength of the bonds between two protein molecules important in cell machinery: Gently tugging them apart with light beams. Last fall, Lang and others demonstrated that light beams could be used to pick up and move individual cells around the surface of a microchip. Now they have applied the optical tweezers to measuring protein microarchitectures, allowing them to study the forces that make cells movable. (source: web.mit.edu)
