Abstract
A method of microfluidic control via localized heating includes providing a microchannel structure with a base region that is partially filled with a volume of liquid being separated from a gas by a liquid-gas interface region. The base region includes one or more physical structures. The method further includes supplying energy input to a portion of the one or more physical structures within the volume of liquid in a vicinity of the liquid-gas interface region to cause localized heating of the portion of the one or more physical structures. The method also includes transferring heat from the portion of the one or more physical structures to surrounding liquid in the vicinity of the liquid-gas interface region and generating an interphase mass transport at the liquid-gas interface region or across a gas bubble while the volume of liquid and the gas remain to be substantially at ambient temperature.
