콜로이드 입자의 자기 조립 과정을 통해 PDMS 미세 유체 칩의 하위 50 Nm의 나노 유체 접합 만들기

We propose a simple self-assembly technique of silica colloidal nanoparticles to create a nanofluidic junction between two microchannels in polydimethylsiloxane (PDMS). Using this technique, a nanoporous bead membrane with a pore size down to ~45 nm was built inside a microchannel and applied to electrokinetic preconcentration of DNA samples.
