Development of embedded metal lines in a plastic electrochemical microfluidic device by blanket mould imprinting

In this paper we introduce a blanket mold imprinting process to prevent complication of the fluid flow and difficulties in producing high pressure seals. In-channel embedded metal lines were also fabricated within the channel allowing electrochemical detections of analytes. Electrochemical microfluidc device has been fabricated on the PET (Polyethylene Terephthalate) substrate by using imprinting method. The resulting devices were applied to microscale chromatographic separation with whole column electrochemical detection. They also were shown to be leak free and stable well in excess of the required operating pressure.
