Solid-ink-based print-and-peel method for microfluidic fabrication: a revisit

Abstract

The print-and-peel (PAP) method enables faster and cheaper fabrication of microfluidic devices, because this non-lithographic method uses a commercial printer to print channel mold patterns onto transparency film for use as a mold for microfluidic device fabrication. This study revisits the solid-ink-based PAP method by characterizing solid link patterns printed on transparency films for cross-sectional shape, height, and surface roughness. In addition, the method was applied to create functional microfluidic devices to show that this low-cost method can be used for microfluidic applications.
