Systems and methods for using a flow cell array are provided herein. A system includes at least one processor coupled to a memory and configured for determining placement of one or more reaction sites on a first component; providing a material for the one or more reaction sites in one or more surface channels of the first component; connecting the first component to a second component to form an array, wherein the one or more surface channels of the first component connect the one or more reaction sites with one or more vias, and wherein the second component comprises the one or more vias connected to multiple sub-surface channels; and aligning the one or more surface channels of the first component with the one or more vias of the second component to form a connection between the first component and the second component.

The present invention provides a device capable of detecting a plurality of items in a specimen using a single optical system. Microstructures holding specific binding reagents in a photocured hydrophilic resin are arranged in a channel, whereby the reagents do not mix during manufacture of the device, and a device capable of multiplex detection can be manufactured.

The present invention provides microfluidic technology enabling rapid and economical manipulation of reactions on the femtoliter to microliter scale.

A method and system for heating and/or inspecting a portable microfluidic assay cartridge for performing an assay includes receiving the assay cartridge on a receiving region of a translatable table under automated control, heating the cartridge, during performance of the assay, with a planar radiant heater plate, the heater plate having an aperture through which an inspection axis extends, and/or inspecting the cartridge using an optical system constructed to inspect the cartridge along the inspection axis by reading a fluorescent light signal which passes through the aperture in the heater plate. In addition, the cartridge moves with movement of the translation table, and the heater plate and optical system may be stationary, and the inspection axis may be fixed.

The present invention provides microfluidic technology enabling rapid and economical manipulation of reactions on the femtoliter to microliter scale.

An operating and reading instrument for performing an assay employing a portable microfluidic assay cartridge, the instrument comprising a translatable table under automated control, the translatable table carrying a receiving region for the portable cartridge and carrying a port system connectable to the cartridge that includes at least one remotely automated valve carried by the translatable table, the valve arranged to apply pressurized flowable substance at selected times to the cartridge while the cartridge is on the translatable table.

A pneumatically driven portable assay cartridge having analyte capture regions associated with microfluidic channels within its interior, the portable cartridge having pneumatic ports clampable against pneumatic ports of an operating instrument for controlled application of positive pressure and vacuum to pneumatic operating channels within the cartridge, the cartridge having a well for receiving sample from a user and microfluidic channels that include pneumatically operated pistons and valves controllable by the pneumatic operating channels to cause all flows of the assay from the reservoirs through reaction regions within the cartridge to on-board waste reservoir during conduct of the assay.

A fluid treatment device is disclosed. The device includes: a cassette including a pre-assembled tubing, the cassette having a flat surface for receiving the tubing, the tubing including at least one flexible tube able to be pinched; at least one pinch valve including a movable pin and a fixed stop for pinching the flexible tube in order to control a fluid flow rate in the flexible tube; wherein the pinch valve is mechanically coupled to the cassette such that the movable pin of the pinch valve describes a trajectory parallel to the flat surface of the cassette when the pinch valve is activated to pinch the flexible tube, and wherein the tubing may be easily, quickly, and cost-effectively installed and replaced. Further disclosed is a fluid treatment method allowing a tubing included in a fluid treatment device according to the disclosure to be easily, quickly, and cost-effectively installed and replaced.
