BIOLOGICAL ANALYSIS SYSTEM AND METHODS
A system for biological analysis includes a housing, a block assembly within the housing having a sample block and a baseplate, a heated cover and a cover carrier. The sample block receives a sample holder comprising an RFID tag. A first drive mechanism generates relative movement between the sample block and the baseplate along a first axis. A second drive mechanism generates relative movement between the heated cover and the cover carrier along a second axis that is different from the first axis. Based on a first command the first drive mechanism releasably engages the sample block and operates the second drive mechanism to releasably engage the heated cover with the cover carrier. The system also includes first and second RFID antennas that receive RFID data from the sample holder RFID tag that is read by at least one RFID reader.
SYSTEMS, METHODS, AND APPARATUS FOR AUTOMATED SELF-CONTAINED BIOLOGICAL ANALYSIS
Systems, apparatus, and methods for conducting amplification-based analyses, including PCR testing. In one illustrative embodiment, a system may include a testing container assembly and a testing unit. The testing container assembly may include a sample collection port, a sample preparation chamber, and a reaction chamber. The sample collection port may include a bottom opening sealed by a plug member. In use, the testing container assembly may be placed in a seat of the testing unit with a sample in the sample collection port, closed by a lid. A plunger may dislodge the plug member and the sample drawn into the sample preparation chamber. Once sample preparation is complete, a channel may be opened, and the prepared sample flows into the reaction chamber which is then sealed. Testing including amplification reactions, may then be performed, followed by detection, as by detecting fluorescent emissions in the reaction chamber.
PERISTALTIC MICROPUMP DRIVEN MICROFLUIDIC PCR CHIP, THIN MEMBRANE MICROPUMP DRIVEN MICROFLUIDIC PCR CHIP
Microchannels include membranes operable with magnets or other actuators to deliver samples to one or more reaction zones defined in the microchannels. Membrane flexing can direct samples to selected reaction zones and each reaction zone can be independently temperature controlled to implement a PCR-based sample analysis.
Method of performing droplet-based assays
Method of analysis. In the method, a first emulsion and a second emulsion substantially separated from one another by a spacer fluid may be formed. The first emulsion, the spacer fluid, and the second emulsion may be flowed in a channel from a fluid inlet to a fluid outlet of a heating and cooling station having two or more temperature-controlled zones, such that each emulsion is thermally cycled to promote amplification of a nucleic acid target in droplets of the emulsion. Amplification data may be collected from individual droplets of each emulsion downstream of the heating and cooling station. A level of the nucleic acid target present in each emulsion may be determined based on the amplification data collected from the individual droplets of the emulsion.
Unitary biochip providing sample-in to results-out processing and methods of manufacture
A biochip for the integration of all steps in a complex process from the insertion of a sample to the generation of a result, performed without operator intervention includes microfluidic and macrofluidic features that are acted on by instrument subsystems in a series of scripted processing steps. Methods for fabricating these complex biochips of high feature density by injection molding are also provided.
Microfluidic cartridge for processing and detecting nucleic acids
A system, configured to facilitate processing and detection of nucleic acids, the system comprising a process fluid container and a cartridge comprising: a top layer, a set of sample port-reagent port pairs, a shared fluid port, a vent region, a heating region, and a set of detection chambers; an intermediate substrate, coupled to the top layer comprising a waste chamber; an elastomeric layer, partially situated on the intermediate substrate; and a set of fluidic pathways, each formed by at least a portion of the top layer and a portion of the elastomeric layer, wherein each fluidic pathway is fluidically coupled to a sample port-reagent port pair, the shared fluid port, and a detection chamber, comprises a portion passing through the heating region, and is configured to be occluded upon deformation of the elastomeric layer, to transfer a waste fluid to the waste chamber, and to pass through the vent region.

COVER MEMBER, METHOD AND TREATMENT MODULE FOR TREATING A BIOLOGICAL SAMPLE ON A SUBSTRATE
A cover member for a substrate supporting a biological sample comprises first and second opposing ends, first and second opposing surfaces, a void in the second surface which, when juxtaposed with a substrate, forms a chamber, and a fluid inlet toward the first end and in fluid communication with the void. The void is bounded by void walls having one or more contoured regions for enhancing fluid movement within the chamber. A treatment module for a biological sample comprises the cover member, a support surface for a substrate bearing the biological sample and clamp means operable to releasably retain the cover member in juxtaposition with the substrate for an incubation period. A method for incubating the biological sample with one or more reagents uses the cover member.
