N2 - We developed a technology for drag reduction in nanochannel by incorporating a superhydrophobic and oleophobic nanostructure. Fused-silica nanopillars with defined dimension and geometry were successfully fabricated and modified hydrophobically. The contact angles of water and hexadecane on the nanopillars were 138.3° and 106.9°, respectively. As a result, The fluid resistance in water was reduced by about 60%. Therefore, reduction of fluid resistance in the nanochannel was verified for the first time. This study will contribute to miniaturization and energy saving in nanofluidic devices.
