The present invention is related to the field of bio/chemical sampling, sensing, assays and applications. Particularly, the present invention is related to how to make the sampling/sensing/assay become simple to use, fast to results, highly sensitive, easy to use, using tiny sample volume (e.g. 0.5 uL or less), operated by a person without any professionals, reading by mobile-phone, or low cost, or a combination of them.

A system for diagnostic testing may include a meter for performing a diagnostic test on a sample applied to a test media, the meter having a housing and an interface for receiving a signal representing coding information, and a container configured to contain test media compatible with the meter, the container having a coding element associated therewith. Additionally, the system may provide a mechanism for removing the meter from an interconnected test container and reattaching it to a new container using on-container coding methods that can recalibrate the meter for the new container of test strips.

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.

The present disclosure relates to a sampling and sensing device and a method of using the sampling and sensing device for collecting and sensing chemical or biological analytes. The sampling and sensing device comprises a handle and a foldable head having a sampling region and a sensing region. A sensor chip may be disposed in the sensing region and a sampling wipe may be disposed in the sensing region. The sampling region is configured to collect an analyte. After the analyte is collected on the sampling region, the sampling and sensing device can be folded to make the sampling region in contact with or face the sensing region to transfer the analyte to the sensing region for analysis.

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.

Among other things, the present invention is related to devices and methods of performing biological and chemical assays, such as but not limited to assay related to analysis of white blood cells.

The present invention is related to the field of bio/chemical sampling, sensing, assays and applications. Particularly, the present invention is related to how to make the sampling/sensing/assay become simple to use, fast to results, highly sensitive, easy to use, using tiny sample volume (e.g., 0.5 μL or less), operated by a person without any professionals, reading by mobile-phone, or low cost, or a combination of them.

Disclosed is a sample collection and detection card. A lower cover of the card is provided with a sample loading chamber capable of accommodating a sampling part of a sampling end, an outlet is arranged at a bottom of the sample loading chamber, and a sample loading area of a test strip is located at the outlet; a fixing structure for fixing a sampling rod to a box is further arranged between the box and the sampling rod, and the sampling part is deformable when the sampling rod is fixed to the box. In embodiments of the present disclosure, the sample loading chamber is arranged on the lower cover, and the sample loading area of the test strip is arranged at the outlet of the sample loading chamber.

Automation compatible removable lids are provided. The removable lids include a top surface surrounded by a peripheral rim. The removable lids further include septal portions configured to receive an extractor, such as a pipette tip, inserted therethrough. The septal portions are further configured to grip the extractor to facilitate lid removal.

Described herein are three-dimensional (3-D) paper fluidic devices. The entire 3-D device is fabricated on a support layer formed from a single sheet of material and assembled by folding the support layer. The folded structure may be enclosed in an impermeable cover or package. Chemically sensitive particles may be disposed in the support layer for use in detecting analytes.
