N2 - This paper presents a nanovalve that uses electrodeposited nanostructures on a solid-state Ag-Ge-Se electrolyte to regulate liquid flow in micro/nano-fluidic channels. The valve uses the extremely rough surface morphology of electrodeposits to manipulate hydrophobicity, thereby closing and opening the nanovalves. Electrodeposited nanostructures can be grown and retracted on the electrolyte surface by applying voltages between 5V and -20V at room temperature. The nanovalve successfully closes and opens de-ionized water (DI) flow in a 20μm tall and 500μm wide microfluidic channel. Closing and opening a single nanovalve takes 5.3 min and 3 min, respectively, with a power consumption of 0.08 mW and 0.17mW, respectively. A triple nanovalve takes 3.8min and 2.5min to close and open, representing a 28% and 17% decrease in valving time as compared to a single nanovalve.
