Abstract:
This invention provides a capillary electrophoresis device in which capillaries are thermally regulated on a thermally responsive electrical path attached to an electrically insulating circuit board. This invention also provides an optical scanner useful for scanning an array of capillaries. A laser, optical detector and optical selector are in an arrangement that allows the optical detector to selectively detect an optical signal from any one or more of the plurality of electrophoresis capillaries.
Abstract:
This disclosure provides an integrated and automated sample-to-answer system that, starting from a sample comprising biological material, generates a genetic profile in less than two hours. In certain embodiments, the biological material is DNA and the genetic profile involves determining alleles at one or a plurality of loci (e.g., genetic loci) of a subject, for example, an STR (short tandem repeat) profile, for example as used in the CODIS system. The system can perform several operations, including (a) extraction and isolation of nucleic acid; (b) amplification of nucleotide sequences at selected loci (e.g., genetic loci); and (c) detection and analysis of amplification product. These operations can be carried out in a system that comprises several integrated modules, including an analyte preparation module; a detection and analysis module and a control module.
Abstract:
The invention provides systems, devices, methods, and kits for performing an integrated analysis. The integrated analysis can include sample processing, library construction, amplification, and sequencing. The integrated analysis can be performed within one or more modules that are fluidically connected to each other. The one or more modules can be controlled and/or automated by a computer. The integrated analysis can be performed on a tissue sample, a clinical sample, or an environmental sample. The integrated analysis system can have a compact format and return results within a designated period of time.

Abstract:
This invention provides a device comprising at least one diaphragm valve actuated by a hydraulic actuation system. The device is comprised in a combination that includes a fluidics layer, an actuation layer and an elastic layer sandwiched between the fluidics layer and the actuation layer, wherein the diaphragm valve comprises: (a) a valve inlet and a valve outlet comprised in the fluidics layer; (b) a valve seat; (c) a diaphragm comprised in the elastic layer, wherein the diaphragm is actuatable to move into contact or out of contact with the valve seat, thereby closing or opening the diaphragm valve; and (d) an actuator comprising: (1 ) a hydraulic conduit comprised at least in part in the actuation layer; (2) a translator; and (3) an incompressible fluid contained within the hydraulic conduit, wherein the incompressible fluid communicates with the translator and with the diaphragm.
Abstract:
In one aspect, this invention provides an article fabricated in one piece comprising at least one aperture through the piece, wherein the aperture defines a non-micro fiuidic volume, and a micro fiuidic channel formed in a surface of the piece onto which the aperture opens, wherein the channel is in fiuidic communication with the aperture, wherein the aperture and the microfluidic channel define a fiuidic circuit.
Abstract:
This invention provides composite plastic articles and methods of making them. The articles can be fluidic or microfluidic devices having fluidic conduits and, optionally, pneumatic conduits that regulate flow in the fluidic conduits. The articles comprise a first substrate coated with a layer of a material that comprises, or onto which have been introduced, reactive groups. For example, the substrate can be a plastic coated with an oxide or a siloxane onto which hydroxyl groups have been introduced. These articles are covalently bonded with other articles comprising reactive groups on their surfaces, for example, polysiloxanes treated to have silanol groups. Certain articles have specified locations on their surfaces that are not bonded to the other piece. For example, the coating can be removed from these locations before bonding. Such locations can be useful as functional elements of various devices, such as valve seats in valves of microfluidic devices.
Abstract:
The invention provides a system that can process a raw biological sample, perform a biochemical reaction and provide an analysis readout. For example, the system can extract DNA from a swab, amplify STR loci from the DNA, and analyze the amplified loci and STR markers in the sample. The system integrates these functions by using microfluidic components to connect what can be macrofluidic functions. In one embodiment the system includes a sample purification module, a reaction module, a post- reaction clean-up module, a capillary electrophoresis module and a computer. In certain embodiments, the system includes a disposable cartridge for performing analyte capture. The cartridge can comprise a fluidic manifold having macrofluidic chambers mated with microfluidic chips that route the liquids between chambers. The system fits within an enclosure of no more than 10 ft 3 , and can be a closed, portable, and/or a battery operated system. The system can be used to go from raw sample to analysis in less than 4 hours.
Abstract:
One aspect of the technology relates to a method comprising the steps of: moving a frame movably holding at least one hollow bore pin having a liquid dispensing tip, such that the liquid dispensing tip of the at least one hollow bore pin moves into a respective well of a set of target wells, and the liquid dispensing tip makes contact with a bottom surface of the respective well; continuing to move the frame after the liquid dispensing tip makes contact, such that the at least one hollow bore pin moves to a particular position (e.g., vertical position) within a range of positions (e.g., vertical positions) relative to and permitted by the frame.
