The corresponding DEP force exerted on individualized SWCNTs at 20 and 100 °C, respectively. The arrows and the quasi-hemicycles denote the direction and value contour of DEP force, respectively. The unit of length is μm. The lengths of the DEP force arrows are proportional to the logarithm of the DEP force value. The outermost quasi-hemicycle contours with a diameter of about 25 μm are corresponding to the DEP force of ~10−16 N. The maximum DEP forces are located at the endpoints of the electrodes
