Two methods of temperature control of a dual-beam optical-tweezers system are compared. In the first method, we used a 975 nm infrared laser to raise the temperature 5.6 degrees C/100 mW in a nonheating (830 nm) optical trap. The temperature increment logarithmically decreases toward the periphery of the heating beam, causing a fluid convection of 8 mum/s inside a 180 microm thick microchamber. In the second method, heating or cooling fluid was pumped through copper jackets that were placed on… CONTINUE READING
