چکیده

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).

Fabrication of Nanopillar Micropatterns by Hybrid Mask Lithography for Surface-Directed Liquid Flow

This paper presents a novel method for fabricating nanopillar micropatterns for surface-directed liquid flows. It employs hybrid mask lithography, which uses a mask consisting of a combination of a photoresist and nanoparticles in the photolithography process. The nanopillar density is controlled by varying the weight ratio of nanoparticles in the composite mask. Hybrid mask lithography was use...

Wafer-scale fabrication of plasmonic crystals from patterned silicon templates prepared by nanosphere lithography.

By combining nanosphere lithography with template stripping, silicon wafers were patterned with hexagonal arrays of nanowells or pillars. These silicon masters were then replicated in gold by metal evaporation, resulting in wafer-scale hexagonal gratings for plasmonic applications. In the nanosphere lithography step, two-dimensional colloidal crystals of 510 nm diameter polystyrene spheres were...

Liquid-phase gallium-indium alloy electronics with microcontact printing.

Liquid-phase electronic circuits are patterned on an elastomer substrate with a microcontact printer. The printer head dips into a pool of a liquid-phase gallium-indium alloy, e.g., eutectic gallium-indium (EGaIn) or gallium-indium-tin (Galinstan), and deposits a single drop on a silicone elastomer substrate. After patterned deposition, the liquid-phase circuit is sealed with an additional laye...

Three-dimensionally-patterned submicrometer-scale hydrogel/air networks that offer a new platform for biomedical applications.

Phase mask interference lithography was employed to fabricate three-dimensional (3D) hydrogel structures with high surface area on neural prosthetic devices. A random terpolymer of poly(hydroxyethyl methacrylate- ran-methyl methacrylate- ran-methacrylic acid) was synthesized and used as a negative-tone photoresist to generate bicontinuous 3D hydrogel structures at the submicrometer scale. We de...
