The present invention relates to a sample collector comprising: an inner flexible collection bag having an opening along its upper edge at least when open for use; and an outer support for supporting the collection bag at its opening. The support has sides that can fold together for storage and open to provide a structure in which one end has a spout and another end has a transverse portion. The sides include fold lines to enable bending of the sides from a storage configuration into an open configuration. The collection bag being connected to the outer support such that on opening of the outer support the bag is held open for collection of a sample.

A nonwoven fabric includes a fiber including a first portion and a second portion connected to the first portion. A first fiber diameter of the first portion is smaller than a reference fiber diameter. A second fiber diameter of the second portion is equal to or greater than the reference fiber diameter. The reference fiber diameter is smaller than 1 m. A ratio of a maximum fiber diameter of the second portion to a length of a linear line connecting both end portions of the second portion is from 1/10 to 1/3.

A system of detecting a blood analyte includes a lateral flow test strip and a test strip holder, the lateral flow test strip located in the test strip holder. The system further includes a meter for receiving the test strip holder.

An automated in situ heat induced antigen recovery and staining method and apparatus for treating a plurality of microscope slides. The process of heat induced antigen recovery and the process of staining the biological sample on the microscope slide are conducted in the same apparatus, wherein the microscope slides do not need to be physically removed from one apparatus to another. The reaction conditions for treating a slide can preferably be controlled independently, including the individualized application of reagents to each slide and the individualized treatment of each slide.

Paper microfluidic devices for the detection of bodily fluids are provided. Such devices can be used, for example, for detection of bodily fluids from or at crime scenes, including blood, saliva, semen, urine, feces, vaginal fluids, and perspiration. Detection can be performed using colorimetric reagents that react when placed in contact with the fluid of interest. A single device can be used to test for multiple bodily fluids at the same time.

An analytical and/or diagnostic device that includes a compartment for reagents stored within the device and uses surface energy gradient coatings to move liquid through fluid passages. The device can include a sampler for collecting a sample, a reaction region for reagents to react with the sample, and a detection region to detect any species of interest present in the sample.

The following description relates to a composite for a harmful material-detecting sensor, which includes a dye having a color-change function by reaction with acid or base and a polymer material, a method for producing the composite for the harmful material-detecting sensor, and a low-cost film-type color change harmful material sensor, which includes the composite for the harmful material-detecting sensor so as to quickly detect a harmful material and can be carried by an individual.

An impedance spectroscopy biosensor is provided that is fabricated on a stretchable substrate. The stretchable substrate is integrated with an impedance biosensor that undergoes cyclic strain without cracking.

An automated in situ heat induced antigen recovery and staining method and apparatus for treating a plurality of microscope slides. The process of heat induced antigen recovery and the process of staining the biological sample on the microscope slide are conducted in the same apparatus, wherein the microscope slides do not need to be physically removed from one apparatus to another. Each treatment step occurs within the same reaction compartment. The reaction conditions of each reaction compartment for treating a slide can preferably be controlled independently, including the individualized application of reagents to each slide and the individualized treatment of each slide.

A method is disclosed for determining concentration of an analyte in a body fluid with a mobile device having a camera. The camera captures an image of an optical test strip having a test field. The analyte concentration value is determined from color formation of the test field. Provided in the mobile device is a correlation for transforming color formation of the test field into analyte concentration. Also provided in the mobile device is an item of clearance information indicating a level of confidence for the correlation. When the item of clearance information indicates a sufficient level of confidence for the correlation, the mobile device indicates to a user that the capturing of the image does not require using a color reference card. Further disclosed are a method of controlling analytical measurements, a mobile device, a system for controlling analytical measurements and computer programs for performing and/or controlling analytical measurements.
