A microfluidic device comprising: an inlet section, for receiving a body fluid sample, the inlet section comprising an inlet port arranged to receive a supply of body fluid; a metering function configured to receive body fluid from the inlet section and comprising a first channel; and a sequent section configured to receive the body fluid from the metering function and comprising a second channel, wherein the first channel comprises a capillary stop valve configured to interrupt or reduce flow of the body fluid therethrough, and a means for visual inspection arranged adjacent to the capillary stop valve, wherein a geometry and/or dimension of the inlet port is configured such that when the supply of body fluid to the inlet port is removed, the Laplace pressure of a body fluid meniscus at the inlet port is higher than a threshold pressure of the capillary stop valve.

Aspects of the invention provide a biological sample collection pad (e.g., for the collection of fecal, liquid or tissue samples). Method of using such pads and analyzing collected samples are also provided.

Reagent devices including a liquid container and a reagent insert are provided. Aspects of the reagent insert include a first dried reagent composition and a second dried reagent composition distinctly positioned on one or more surfaces of a solid support. Also provided are methods of making and using the reagent device or reagent insert, as well as systems and kits including the same.

A microfluidic sensor for the detection of analytes in objects includes a contact surface that may be attached to a surface of the object, an inlet hole in the contact surface for the entry of fluids emitted by the object, and a first reservoir which stores an ionic fluid in the form of a polymer matrix. The polymer matrix includes a reactive substance which changes colour when it enters into contact with the analytes of the fluids emitted by the object. It further includes at least one first microfluidic duct which connects the inlet hole to the first reservoir. A system for the detection of analytes, a method for the manufacture of the microfluidic sensor and the use of the microfluidic sensor for the detection of analytes in works of art are also related.

The present exemplary embodiments provide a sample separation device which applies an electric field to a selective ion permeable layer based on origami to concentrate a target material in a specific area and concentrates a target material and separates a non-target material through a filter layer in which a paper is compressed to adjust a size of micro pore.

A module for processing fluids includes one or more collapsible fluid chambers supported on a substrate, a compression element supported on the substrate and configured to be movable with respect to the one or more chambers, and an actuating element coupled to the compression element and configured to effect movement of the compression element relative to the one or more fluid chambers to collapse each fluid chamber by compressing the fluid chamber between the compression element and the substrate as the compression element moves over the fluid chamber. A method for motivating a fluid out of a fluid chamber comprises the steps of providing a module that includes one or more collapsible fluid chambers supported on a substrate, a compression element supported on the substrate and configured to be movable with respect to the one or more chambers, and an actuating element coupled to the compression element and configured to effect movement of the compression element relative to the one or more fluid chambers and moving the actuator element to move the compression element across at least a portion of t substrate and compress the fluid chamber, thereby motivating the fluid out of the fluid chamber.

Single-use diagnostic consumables for use in performing multiple analyses on a fluid sample are provided. The diagnostic consumables include a first sensing region configured for analysis of at least one analyte in a fluid sample that has been received by the diagnostic consumable. The diagnostic consumable further includes a fluid transport material configured to flow a portion of the fluid sample into a second sensing region fluidically connected to the fluid transport material and configured for performing a second analysis of the fluid sample. Methods for performing multiple analyses of a fluid sample on a single-use diagnostic consumable are also provided.

The disclosure is directed to a device that includes an upper container configured to receive a fluid sample collected from a mammal into a first opening, the first opening opposite a second opening and a membrane covering at least a portion of the second opening, the membrane configured to allow transmission of a portion of the fluid sample through the membrane.

A biochemical detection device is revealed. The biochemical detection device includes a cap and a base arranged at two ends of a test tube correspondingly and a driving member disposed on the base. A sample-mounting slot and a test-paper-mounting slot separated from each other are formed in the test tube. After sampling, a sample obtained is placed into the sample-mounting slot and mixed with an extraction solution therein. A thin-film on the sample-mounting slot is penetrated by the driving member to allow the extraction solution mixed with the sample flowing into a cavity of the test tube to react with a test strip in the test-paper-mounting slot. The test cost is reduced and the detection efficiency is improved due to simple structure and easy operation. Moreover, the sample and the extraction solution are sealed in the test tube to prevent environmental pollution caused by spread of viruses.

A device for collecting, preserving and storing a sample of biological fluid comprising a porous medium for collecting and maintaining the membrane integrity of the eukaryotic cells contained in the sample, and their constituents is disclosed, the medium comprising at least 80% by weight of artificial components, advantageously at least 85%, preferably at least 90% of a total weight of the medium; and having a mean flow pore size (MFP) of at least 3 μm.
