The technique is to make use of gentle to create a temperature gradient and exploit the thermophoretic migration of matter for optical trapping. The team additional integrated thermophoresis with laser cooling to develop opto-refrigerative tweezers to avoid thermal damages for noninvasive optical trapping and manipulation. When a cluster of microparticles are trapped inside a monochromatic laser beam, the group of the microparticles inside the optical trapping is closely dependent on the redistr...
