Systems and methods for conducting designated reactions utilizing a base instrument and a removable cartridge. The removable cartridge includes a fluidic network that receives and fluidically directs a biological sample to conduct the designated reactions. The removable cartridge also includes a flow-control valve that is operably coupled to the fluidic network and is movable relative to the fluidic network to control flow of the biological sample therethrough. The removable cartridge is configured to separably engage a base instrument. The base instrument includes a valve actuator that engages the flow-control valve of the removable cartridge. A detection assembly held by at least one of the removable cartridge or the base instrument may be used to detect the designated reactions.

There is set forth herein a device comprising structure defining a detector surface configured for supporting biological or chemical substances, and a sensor array comprising light sensors and circuitry to transmit data signals using photons detected by the light sensors. The device can include one or more features for reducing fluorescence range noise in a detection band of the sensor array.

Detector with reduced fluorescence range noise

A flow cell including inlet and outlet ports in fluid communication with each other through a flow channel that extends therebetween. The flow channel includes a diffuser region and a field region that is located downstream from the diffuser region. The field region of the flow channel directs fluid along reaction sites where desired reactions occur. The fluid flows through the diffuser region in a first flow direction and through the field region in a second flow direction. The first and second flow directions being substantially perpendicular.

Flow cells and corresponding methods are provided. The flow cells may include a support frame with top and back sides, and at least one cavity extending from the top side. The flow cells may include at least one light detection device with an active area disposed within the at least one cavity. The flow cells may include a support material disposed within the at least one cavity between the support frame and the periphery of the at least one light detection device coupling them together. The flow cells may include a lid extending over the at least one light detection device and coupled to the support frame about the periphery of the at least one light detection device. The lid and at least a top surface of the at least one light detection device form a flow channel therebetween.

Embodiments provided herewith are directed to self-assembled methods of preparing a patterned surface for sequencing applications including, for example, a patterned flow cell or a patterned surface for digital fluidic devices. The methods utilize photolithography to create a patterned surface with a plurality of microscale or nanoscale contours, separated by hydrophobic interstitial regions, without the need of oxygen plasma treatment during the photolithography process. In addition, the methods avoid the use of any chemical or mechanical polishing steps after the deposition of a gel material to the contours.

A biosensor is provided including a detection device and a flow cell mounted to the detection device. The detection device has a detector surface with a plurality of reaction sites. The detection device also includes a filter layer that is configured to at least one of (a) filter unwanted excitation light signals; (b) direct emission signals from a designated reaction site toward one or more associated light detectors that are configured to detect the emission signals from the designated reaction site; or (c) block or prevent detection of crosstalk emission signals from adjacent reaction sites.

A stack of fluidics layers of a microfluidic cartridge for sequencing nucleic acid molecules includes a sequencing chamber layer having a sequencing chamber area configured for carrying out clustering and sequencing reactions, and a sequencing chamber bottom layer disposed under the sequencing chamber layer. The sequencing chamber bottom layer has an opening configured to hold an image sensor with the image sensor having an active area disposed under the sequencing chamber area. The sequencing chamber area spans substantially all of the active area of the image sensor. The stack of fluidics layers includes a flexible printed circuit board (PCB) layer under the sequencing chamber bottom layer, and a fluidics channels layer disposed under the flexible PCB layer. The fluidics channels layer includes fluidics channels that are configured to deliver reactants to the sequencing chamber area. The fluidics channels do not substantially overlap with the active area of the image sensor.
