MICROFLUIDIC BIOSENSOR FOR ALLERGEN DETECTION
20170341077 · 2017-11-30 ·

The present application relates to biosensors and methods for detecting and/or quantifying a target analyte such as a target allergen or toxin. In some embodiments, the biosensors use an allergen- or toxin-binding molecule conjugated to a fluorescent label such as a quantum dot that adheres to and is quenched by graphene oxide in the absence of the allergen or toxin.

System and method for isolating and analyzing cells

A system and method for isolating and analyzing single cells, wherein the system includes: an array of wells defined at a substrate, each well including an open surface and a well cavity configured to capture cells in one of a single-cell format and single-cluster format, and a fluid delivery module including a fluid reservoir superior to the array of wells through which fluid flow is controlled along a fluid path in a direction parallel to the broad face of the substrate; and wherein the method includes: capturing a population of non-cell particles into the array of wells in single-particle format; releasing, from the non-cell particles, a set of probes into the array of wells; capturing a population of cells into the array of wells in single-cell format; releasing biomolecules from each captured cell into the array of wells; and generating a set of genetic complexes comprising the biomolecules associated with a single captured cell and a subset of probes within individual wells of the array of wells.

20230173493 · 2023-06-08 ·

An assay plate is provided. The assay plate has a body with a plurality of reservoirs formed therein. The reservoirs are shaped and aligned in the body in an orientation to induce drainage of fluids contained therein in a desired direction. A plate array and a funnel array forming an assembly for pooling of samples contained in the assay plate is also provided.

DEVICES FOR COLLECTING BIOLOGICAL SAMPLES

Disclosed herein are devices, apparatus, systems, methods and kits for collecting and storing a fluid sample from a subject. A device for collecting the fluid sample can include a housing comprising a recess having an opening, a vacuum chamber in the housing and in fluidic communication with the recess, and one or more piercing elements that are extendable through the opening to penetrate skin of the subject. The vacuum chamber can be configured for having a vacuum that draws the skin into the recess. The recess can be configured having a size or shape that enables an increased volume of the fluid sample to be accumulated in the skin drawn into the recess.

AGGREGATION-ASSISTED SEPARATION OF PLASMA FROM WHOLE BLOOD

Methods for separating blood plasma from whole blood in the absence of performing centrifugation are provided. The method combines mechanical filtration and blood cell aggregation and is adapted for use in POC clinical testing.

Hematology test slide

A hematology test slide has the same or similar dimensions as a chemical reagent test slide and an immunoassay test slide so that it may be used with these other slides on a single clinical instrument. The hematology slide includes, in order from top to bottom, a slide housing having a top housing member, a top cover slip, a U-shaped, transfer tape spacer, a bottom cover slip, a base gasket and a base plate. The U-shaped spacer has a curved end portion which defines a sample deposit area, where a blood sample is pipetted thereon, and a pair of straight, parallel, spaced apart legs extending from the curved end portion. The legs define a read area. A blood sample deposited on the hematology slide at the sample deposit area will flow by capillary action to the read area, where optical measurements are made on the sample.

Device for the capillary transport of liquids

Disclosed is a device for the directed capillary transport of liquids, comprising at least two capillaries (8, 9, 33, 54, 55), the at least two capillaries (8, 9, 33, 54, 55) being designed such that the liquid can be transported in at least some regions in a passive, directed and capillary manner, characterised in that at least two of the capillaries (8, 9, 33, 54, 55) are interconnected in the direction of transport of the liquid via at least one capillary passage conduit (20, 23, 28, 29, 34, 40, 41, 59, 63). The invention is intended for use in the separation of components from a fluidic substance and/or in oil/water separation. A production method is characterised in that at least one part of the capillary structure is generated by means of laser irradiation, by means of a moulding tool, in particular a sintering mould, by means of a milling process, in particular by means of a micro-milling process, or by means of EDM.
