Abstract

We report a microfluidic valve based on a reversible hydrophobicity effect via the growth and retraction of nonvolatile nano-textured dendritic silver filaments on the surface of a solid electrolyte. A 6 V DC bias grows or dissolves, depending on the polarity, filaments which are tens to hundreds of nanometers in height. The valving function of these nano-filaments, which occurs within approximately 25 sec, was demonstrated by monitoring the fluid flow in a 250 m wide, 25 m deep PDMS-enclosed channel.
