Plasma Etching for Fabricating Microfluidic Devices with Patterned Monolayers

By fabricating microfluidic devices via (covalent) plasma microcontact patterning (PµCP) and replica molding, we were able create β-CD patterns inside a microfluidic channel. Chemical reactivity and reusability of the devices were validated through host-guest interactions with diadamantane functionalized Cyanine 5 dye (Cy5-Ad2).
