ANALYSIS UNIT FOR A TRANSPORTABLE MICROFLUIDIC DEVICE, IN PARTICULAR FOR SAMPLE PREPARATION AND MOLECULE ANALYSIS
An analysis unit formed by an analysis body housing an analysis chamber and having a sample inlet and a supply channel configured to fluidically connect the sample inlet to the analysis chamber. Dried assay reagents are arranged in the analysis chamber and are contained in an alveolar mass. For instance, the alveolar mass is a lyophilized mass formed by excipients and by assay-specific reagents.
PILLAR STRUCTURE FOR BIOCHIP
The present invention relates to a pillar structure for a biochip. The pillar structure for a biochip according to the present invention is provided to form a biochip for analyzing a sample, which is a biological micromaterial such as a cell, together with a well plate configured to receive a culture solution, and the pillar structure includes: a pillar part having a seating surface on which a cell for culture is placed, and a light irradiation surface configured to be irradiated with light for observing the cell placed on the seating surface; and a plurality of holder parts extending in a state of being spaced apart from the pillar part and having an opening between the adjacent holder parts so that the culture solution is introduced between the holder parts.
Methods and systems for cell-based non-invasive prenatal testing
Methods and systems are provided for isolating fetal cells from a maternal blood supply in order to perform non-invasive prenatal testing. In one example, a system for non-invasive prenatal testing includes a substrate coated with a cell-capturing surface, the cell-capturing surface including an array of pillar-like structures, each pillar-like structure including a plurality of intersecting arms.
ISOLATION TUBE
A separation container for extracting a portion of a sample for use or testing and method for preparing samples for downstream use or testing are provided. The separation container may include a body defining an internal chamber. The body may define an opening, and the body may be configured to receive the sample within the internal chamber. The separation container may further include a seal disposed across the opening, such that the seal may be configured to seal the opening of the body, and a plunger movably disposed at least partially inside the internal chamber. The plunger may be configured to be actuated to open the seal and express the portion of the sample.
APPARATUS AND METHODS FOR BUBBLE TRAPS IN FLUIDIC DEVICES
Fluidic devices that include bubble traps are provided. A substrate for a fluidic device includes a first channel to carry a fluid; a chamber, coupled to the first channel, to receive the fluid from the first channel, the chamber having a top and a bottom; a second channel, coupled to the chamber, to receive the fluid from the chamber; and a plurality of barriers adjacent to the top of the chamber. The plurality of barriers inhibit bubbles in the fluid from entering the second channel. Methods for manufacturing and using fluidic devices that include bubble traps are also provided.
PRECISE FLUID INPUT CONTROL FOR POINT-OF-CARE DEVICES
Devices and methods for controlling collection of liquid sample are described. In an example, a microfluidic device can include an analytical device and an actuator. The actuator can be connected to the analytical device. The actuator can be operable to absorb fluid. The actuator can guide the absorbed fluid to an input layer of the analytical device. The actuator can deform in response to an occurrence of an absorption condition. A degree of deformation of the actuator indicates a volume of fluid collected by the analytical device.
Sample analyzer system with a sample vessel having opaque and translucent portions
An embodiment of the present disclosure is a sample vessel for a holding a sample for analysis by a sample analyzer. The sample vessel includes a body that includes a bottom, an open top spaced from the bottom along a first axis, a side wall that extends from the open top to the bottom, and an interior chamber for holding a sample and that extends from the open top toward the bottom along the first axis. The body includes an opaque portion, a first translucent portion, and a second translucent portion spaced from the first translucent portion a distance that extends along a second axis that is perpendicular to the first axis. The first and second translucent portions are each disposed along the bottom of the body.
Powered positive displacement pipette assembly
Described are exemplary embodiments of a handheld, powered positive displacement pipette assembly, including a plurality of syringes of different volumes and a powered positive displacement pipette having unique mechanisms for the retention, identification and ejection of said syringes.
SYSTEM FOR RAPID ON-SITE TESTING FOR AIRBORNE AND OTHER PATHOGENS
A simplified system for air sample collection and analysis for the presence of airborne pathogen is disclosed. An extraction device is used for extracting biomaterial previously deposited on the surface of a capture element of a sampling device, the capture element being of a select cross section and size. The extraction device comprises an upwardly opening head being wider at a top and narrower at a central opening at a bottom. An elongate cavity is attached to the enlarged head at the bottom extending downward from the head and closed at a bottom end to define an interior space, the cavity having a cross section corresponding to the cross section of the capture element and of a slightly larger size than the size of the capture element. An extraction fluid is in the cavity interior space. In use, insertion of the capture element through the head into the elongate cavity extrudes the extraction fluid liquid through the interface between the head and the elongate cavity and provides a fluidic shearing force that serves to solubilize biomaterial from the surface of the capture element.
Analyte sensor package with dispense chemistry and microfluidic cap
A sensor system includes an assay chamber configured to receive a fluid sample. Dispense chemistry disposed within the assay chamber. A first electrode structure includes at least one conductive element and a second electrode structure proximate to the first electrode structure is configured to transmit an electrical signal through the fluid sample. The first electrode structure is configured to receive the electrical signal transmitted through the fluid sample and responsively generate a sense signal. The sense signal being indicative of an interaction of the fluid sample with the dispense chemistry. A controller is electrically coupled to the first electrode structure and configured to identify at least one analyte in the fluid sample based on at least the sense signal generated by the first electrode structure. The first electrode structure is embedded within a base substrate and the second electrode structure is embedded within a microfluidic cap that is coupled to the base substrate.
