MICROFLUIDIC DEVICES AND METHODS OF MANUFACTURE THEREOF

摘要

A microfluidic device comprising: a substrate having a microfluidic channel, an electrically conductive feature comprising an electrically conductive layer arranged on a primer layer and positioned with reference to the microfluidic channel, wherein the primer layer comprises: (i) an organic polymer selected from the group consisting of: (a) a homopolymer or copolymer including a vinyl lactam repeating unit, (b) a cellulose ether; (c) polyvinyl alcohol; and (d) unmodified or modified gelatin; and (ii) a porous particulate material, the organic polymer being dispersed in the porous particulate material, is provided. Methods for manufacturing the microfluidic devices and their use in a number of applications are also provided.

1. A microfluidic device, comprising:
a substrate having a microfluidic channel; and an electrically conductive feature comprising an electrically conductive layer arranged on a primer layer and positioned with reference to the microfluidic channel, wherein the primer layer comprises a polymer and a porous particulate material, and the porous particulate material is dispersed in the polymer, and wherein the microfluidic channel comprises a side wall portion that joins an upper surface of the substrate at a rim and a lateral separation δ exists between the rim of the microfluidic channel and the edge of the electrically conductive layer.
