Abstract:We developed a novel method to control two-phase flow in nanochannels using regulating microchannels connected to the nanochannels. The flow rate inside a nanochannel can be regulated based on the pressure drops along the channel network. Stable flows with flow rates as low as 10-5 µL.min-1 (< pL.s-1) can be obtained for both oil and water phases using a conventional syringe pump. We also demonstrate two-phase nanofluidics by confluence of two immiscible liquid flows in nanochannels
