A cartridge is for a detection of a sample or a first component, wherein the sample includes the first component and a second component. The cartridge includes a first injection chamber, a second injection chamber, a separation chamber, a collection chamber and a first detection chamber. The first injection chamber and the second injection chamber are adapted for injecting the sample or the first component. The separation chamber is connected to the first injection chamber, and the sample injected from the first injection chamber is adapted to be separated into the first component and the second component in the separation chamber. The collection chamber is connected to the separation chamber and the second injection chamber. The first detection chamber is connected to the collection chamber. A biological detection system is further provided.

An example system includes an array of retaining features in a microfluidic cavity, an array of thermally controlled releasing features, and a controller coupled to each releasing feature in the array of releasing feature. Each retaining feature in the array of retaining features is to position capsules at a predetermined location, the capsules having a thermally degradable shell enclosing a biological reagent therein. Each releasing feature in the array of releasing features corresponds to a retaining feature and is to selectively cause degradation of the shell of a capsule. Each releasing feature is to generate thermal energy to facilitate degradation of the shell. The controller is to selectively activate at least one releasing feature in the array of thermally controlled releasing features to release the biological reagent in the capsules positioned at the retaining feature corresponding to the activated releasing feature.

Disclosed is a measurement apparatus including: a support mechanism configured to support a cartridge in which a chamber is formed, the chamber being configured to store a measurement sample that generates light an intensity of which varies depending on an amount of a test substance; a photodetector configured to detect the light generated from the measurement sample stored in the chamber; and a reflection member provided between the photodetector and the cartridge supported by the support mechanism, the reflection member having an inner face, the reflection member being configured to reflect, at the inner face, the light generated from the measurement sample stored in the chamber, and guide the light to the photodetector, wherein the reflection member is configured to have an area surrounded by the inner face, the area decreasing from a side where the cartridge supported by the support mechanism is provided toward a side where the photodetector is provided.

Disclosed is a chemiluminescence measurement apparatus that includes: a support member configured to support a cartridge for measuring a test substance contained in a specimen by chemiluminescence measurement; a motor configured to rotate the support member so as to rotate the cartridge such that a process required for the chemiluminescence measurement proceeds in the cartridge; and a light receiver configured to receive light generated by chemiluminescence in the cartridge that is supported by the support member rotated by the motor. The cartridge supported by the support member and a light receiving surface of the light receiver are disposed inside a dark space surrounded by a light-shielding portion, and the motor is disposed outside the dark space.

Disclosed is a detection apparatus that transfers magnetic particles through a plurality of chambers in a cartridge which includes the plurality of chambers and a channel connecting between the plurality of chambers, and that causes the magnetic particles to carry a complex of a test substance and a labelling substance, to detect the test substance on the basis of the labelling substance in the complex. The detection apparatus includes: a rotation mechanism configured to rotate the cartridge about a rotation shaft; a magnet configured to collect the magnetic particles in the chambers; a movement mechanism configured to move the magnet in a direction different from a circumferential direction of a circle in which the rotation shaft is centered; a detector configured to detect the test substance; and a controller programmed to control the rotation mechanism and the movement mechanism so as to transfer the magnetic particles from one of the chambers to another one of the chambers.

The present invention generally relates to a wearable electronic device that collects information about test sample using an optical sensor. The wearable device photographs and analyzes one or more organic samples placed on one or more immunoassay regions of a test strip in order to reveal information about the sample. The wearable electronic device may also sequentially photograph a plurality of individual organic samples applied to different immunoassay regions of a test strip.

The present invention provides a novel target analysis chip and analysis method for directly detecting a target such as a microRNA without performing PCR.

Verification plates for a bacterial endotoxin reader are provided, namely a temperature verification plate (TVP) and optical verification plate (OVP). The TVP has a body configured to be placed on a spindle of said reader and rotated by said spindle. The body has a temperature verification circuit with a temperature sensor and a temperature indicator. The temperature sensor is configured to measure a temperature of the body rotated by the spindle of the reader. The temperature indicator optically represents a value of the temperature measured by the temperature sensor. The temperature indicator is readable by an optical bench of the reader. The OVP has a body with a plurality of apertures located along a periphery that line up with an optical bench of the reader. Light produced by a light source of the reader can pass through the aperture and an intensity measured by a photodetector of the reader.

Platforms for enzymatic assays for biomarkers, including systems, methods, and measuring devices by which a biomarker, such as creatinine, is measured using a small amount of biological fluid, such as blood, plasma, or serum. The measuring device or biosensor can be a test strip including a layered active component assembly positioned between two outer layers which enables multi-step enzymatic reactions operating in kinetic and/or endpoint (in which the reaction is allowed to near completion), and generally includes multiple layers with primary enzyme(s), coupling enzyme(s), and reagents to produce an optical signal correlated to the concentration of a biomarker in the sample. The test strip can be read using a portable optical reader coupled to a smart phone or tablet.
