Electrical and fluidic interconnections to the chip are made using a custom built connection block, machined from PEEK polymer. Fluidic and electrical connections are made by clamping the chip within the block. Spring loaded connectors are used to make contact with the chip electrodes and miniature 0-rings used to seal the fluidic connection between the block and chip. Microfluidic tubing and connectors are used to connect the PEEK block to the sample, waste and wash reservoirs. The connector block is mounted on a PCB which has the impedance detection circuitry and the...

Microfluidic Boards Microfluidic board interconnection technologies seek to mimic the electronic printed circuit board for ease of use, reliability, and versatility. In microfluidic board technologies, the substrate contains the passive microfluidic channels and reservoirs, with active components (e.g., sensors, valves) mounted on top (e.g.. Ref. [2]) (see Fig. 1) similarly to electronic components mounted on a printed circuit board (PCB) or multichip modules (MCM) in surface-mount technologies (SMT). Electronic coimections between components are provided on top of the board, while fluidic interconnection is usually provided in the board material itself. Microfluidic circuit boards can be made from a variety of materials, including silicon, glass, and polymers, e.g., polydimethylsiloxane (PDMS), epoxy, or polymethyl methacrylate (PMMA). Microfluidic boards can be as simple...

Novel applications for microfluidic devices in chemistry, biology, and medicine are emerging at a rapid pace, and such devices are increasing in complexity. All of these devices share the need to interface micro channels with the macro world. Interfacing and packaging issues present some of the most critical obstacles to successful microfluidic devices [1]. A wide variety of ideas has emerged for producing these fluidic interconnects [2, 3]. The need for an interface port for access to the micro channels is common to all interconnect concepts.
