Abstract
Nanofluidic devices are promising for interdisciplinary applications that require precise manipulation of extremely small amount of liquid. Generally, high driving pressure is needed to ensure continuous flow in extended-nano channels with size ranging of 10-1000 nm because of their high pressure loss. To miniaturize nanofluidic system, we report a novel heat-driven nanofluidic pump using large capillary force in nanospace and optimized evaporation. Continuous water flow is successfully driven into nanochannels without external pressure pumping. This study will contribute to miniaturize the pumping system to drive liquid to nanospace overcoming its large pressure loss.
