Abstract: A cartridge assembly, and method of using the same, is provided. The assembly includes a sample processing card and a substrate attached thereto. The card has an injection port for receiving a test sample; at least one metering chamber; a mixing material source for introducing mixing material(s) to the metering chamber; fluid communication channels fluidly connecting the injection port and the mixing material source to the metering chamber; and at least one output port for delivering the test sample to a sensor (e.g., GMR sensor). The substrate has associated therewith: the sensor for sensing analytes in the test sample; electrical contact portions for an electrical connection with a reader unit; and a memory chip. The assembly further includes a pneumatic interface with port(s) and corresponding communication channel(s) fluidly connected to card.

Abstract: Synthesizing polymeric sheets in a slit fluidic channel by projection of a pulse of illumination to the channel. A slit channel can include a polymeric device with a plane's width larger than 1 mm. A glass plate is placed above the channel to prevent the channel from sagging. A photocurable prepolymer is flowed through the channel. The flow is paused and an illumination is projected to the channel through a photomask, produces a polymer sheet. The polymer sheet is then flushed out by resuming the flow. This process is repeated enabling continuous synthesis of polymeric sheets. The sheets can obtain any patterns defined by the photomask design, such as micropores and other geometrical patterns. These polymer sheets can be used in many emerging areas of technologies such as lab-on-a-chip, tissue engineering and organic electronics.
