Abstract

We report a novel method for formation of pressure driven parallel two phase flow in extended nanochamiel (10-1000 nm). A partial modification method by molecular ablation to spatially control the surface wettability in nanochamiel was developed using the evanescent wave, which illuminates a region shorter than the optical wavelength. This method suggested a potential to form the parallel two phase flow by controlling an interface between water (aqueous phase) and dodecane (organic phase), which showed specific property of 3 times higher Laplace pressure at 500 nm channel compared to microchamiels. The present study will contribute to develop nanofluidic systems using multi phase flows for chemical applications.
