Abstract

Dense arrays of vertically aligned carbon nanofibers are being used as membranes within fluidic structures. Size-dependent transport, perpendicular to the orientation of the fibers, can be controlled based on the wall-to-wall spacing of the individual fibers. The combination of size fractionation and chemical specificity can allow such membranes to selectively transport analytes. Further, addition of electrically addressable carbon nanofibers adds another dimension to controlling transport. However, integrating features across multiple length scales presents significant challenges. Here we address various approaches towards integrating nanoscale structures within fluidic devices. Ultimately, the biologically inspired design of VACNF structures will be useful for performing chemical separations and for mimicking the properties of natural membranes.
