Title: Slip length enhancement in nanofluidic flow using nanotextured superhydrophobic surfaces

In our study, the development of highly efficient nanofluidic devices necessitates means for enhancing and controlling fluid transport under confinement. We show experimentally that significant interfacial drag reduction in nanoscale channels can be obtained with hydrophobic arrays of conical textures tapering to a radius of less than 10 nanometer at their tip. Finally, this geometry maximizes interfacial slippage by trapping a highly resilient air layer at the solid/liquid interface.
