An apparatus for estimating blood concentration of an analyte may include a sweat collector configured to collect sweat from a skin surface of a user. The apparatus may include an optical sensor configured to emit light rays of different wavelengths towards the collected sweat, and detect an optical signal reflected by the collected sweat. The apparatus may include a processor configured to estimate the blood concentration of the analyte based on the detected optical signal.

A CMOS-based chip having one or more sensing modalities that are able independently to detect multiple metabolites present in a biological sample. The multiple sensing modalities may be provided at different locations with respect to the chip, whereby the chip can simultaneously detect a plurality of metabolites by measuring behaviour of a test material in the different locations. The chip may utilise paper as a transport mechanism for the sample. The paper either conveys the sample to the different locations or itself provides discrete testing zones in which different metabolites can be independently detected. With this technique, multiple metabolites may be measured in real time using a small scale point-of-care device.

The method for detecting a target component by using a mobile terminal comprises: detecting a target component by using test strips (100) to obtain chromogenic test strips (100); arranging the test strips (100) around a same circle center at equal angles to obtain an arrangement ring of test strips (100), positioning identifiers being provided on an area outside the test strips (100) on the arrangement ring of the test strips (100); performing image acquisition on the arrangement ring of the test strips (100) by using a mobile terminal, and uploading an acquired image to a data processing center, correcting the acquired image according to the positioning identifiers; determining the positions of a personalized mark area and a result display area of each test strip (100) in the image; performing segmentation to obtain images of the personalized mark area and the result display area of each test strip (100); calculating a chromogenic result of the result display area, and obtaining a test result of the target component; and outputting the test result of the target component and displaying the test result on the mobile terminal.

A fluorescence imaging device includes a display unit that displays an operation screen receiving an operation input, and the display unit displays a setting operation screen including a parameter setting field in which a parameter relating to blue shift correction for correcting shade of a sample image caused by a difference in an incidence angle of fluorescence emitted from each sample at each position where the fluorescence is incident on an optical filter is to be set.

The present invention teaches an apparatus for consistent and accurate on-site readings of fluorescence signals of coronavirus test result, with which a user directly reads a fluorescent light qualitatively instead of using electronic sensors. The fluorescent light is excited from a fluorescent source in a site of interest in a target assay. The device comprises a light source for generating an excitation light for exciting the fluorescent source of the target assay to generate a fluorescent light, a component for accurately transmitting the excitation light and the fluorescent light with less noise or reflection, a component for consistent detecting of the fluorescent source by bare eyes with minimal health risks, and a user control system that requires minimal training.

An optical module (100) for reading a test region of an assay. The optical module comprises: a first light source (101) for illuminating the test region of the assay; an optical detector (103), comprising an optical input for receiving light emitted from the test region and an electrical output; a substrate (104) for mounting the first light source (101) and the optical detector (103); and a housing (105) comprising: a first opening (106) for providing a first optical path from the first light source (101) to the test region (103); wherein the housing (105) and the substrate (104) enclose and positionally align the first source (101) and the optical detector (103) relative to the first opening (106). The housing (105) may comprise one or more legs (108), such as a flexible hook portion which secures the housing (105) to the substrate (104) with a snap-fit engagement, extending from a first and/or second outer surface of the housing (105) in a vertical direction. Beneficially, the snap-fit engagement provided by the flexible hook portion allows the housing to be aligned and secured without the need to use glue or for example a screw and thread that can be difficult to control and/or risks misalignment of the housing.

A lateral flow test system having an optical reader, a lateral flow cartridge and a computer system is provided. The lateral flow cartridge includes a porous test strip with a reading window into the porous test strip exposing an exposed zone of the porous strip. The optical reader has a reader housing and a slot for inserting the cartridge into the reader housing. The optical reader has an illumination arrangement adapted for illuminating the exposed zone of the porous strip when the cartridge is inserted into the slot. The optical reader further has a video camera configured for acquiring a series of digital images comprising the exposed zone of the porous strip. The computer system receives sets of pixel data representing the plurality of consecutive digital images and calculates wetting progress along the length of the exposed zone of the porous strip based on the sets of pixels data.
