Abstract

We succeeded in fabrication of a free accessible microchannel using an air-liquid interface. To pattern the air-liquid interface in the microfluidic chip, we utilized nano-geometric surface which encloses micropatterned massive nanopillars to enhance the wettability of the surface, which was fabricated by using the hybrid mask lithography technique. Novelties of this paper are shown as follows. (1) The contact angle of surface can be adjusted in wide range by fabricating the nano-geometric surface. (2) The free accessible microchannel was achieved by nano-geometric surface. (3) We succeeded in manipulation of a microparticle in the air-liquid interface microchannel by the magnetically driven microtool (MMT).
