At the heart of this approach is a two-dimensional array of microscale containment-cells consisting of closely spaced (10’s-100’s nm) electrofluidic carbon nanofibers (ECNFs). These vertically oriented ECNFs include a highly conformal hydrophobic dielectric coating. Cells of ~250x250 _m perimeter are electrically controlled by an underlying thin film transistor. The entire array is top-sealed and forms a ~10 _m high microfluidic channel. This creates a 2D array of cells capable of pumping an aqueous phase and one or more immiscible phases. Every cell is inherently capable of multiplexing nano- and micro-scale separation based on size, mass, surface energy, ionic charge, and location in a 2D array. Separations scientists will be provided an exciting new tool with greatly improved agility, throughput, and resolution. |
