抄録

We report establishment of a nm-partial hydrophobic modification method by focused ion beam (FIB) and formation of parallel aqueous/organic two-phase flows in extended-nanochannels by control of liquid-liquid interface. Using the parallel two-phase flow, we demonstrated solvent extraction by integrating phase confluence, extraction and phase separation into 25 fL volume. Due to 103 times/sec interaction between solute molecules and surface by diffusion in 100 nm space, extraction of lipid into the organic phase was completed within 4.5 ms. The ultra high performance compared to microfluidics will greatly contribute to novel applications such as single cell analysis.
