The idea of using light beams as tweezers to manipulate cells and tiny objects has been around for at least 30 years. And now, the MIT researchers have found a way to combine this powerful tool for moving, controlling and measuring objects with the highly versatile world of microchip design and manufacturing. It is about a way to use a “tractor beam” of light to pick up, hold, and move around individual cells and other objects on the surface of a microchip.
This microscopic particles can be steered through the tiny channels of a microfluidic chip using light. As it is known, microfluidic chips contain microscopic tubes that can be used to ferry cells and particles around for chemical or biological experimentation. Controlling fluids and particles at small scales is difficult, however.
