Functional material for testing liquid sample

A functional material for testing a liquid sample includes a based material in a sheet shape and a channel part provided on a mounting surface of the base material wherein the channel part is composed with water-permeable fibers having permeability, and water-impermeable fibers having impermeability. The water-permeable fibers and the water-impermeable fibers are arranged along the longitudinal direction of the channel part, forming voids wherein the voids are in a mesh structure in which one of the voids connects to another of the voids such that the empty spaces are linked from a base end to a tip end of the channel part. A thickness of the channel part is ranged from 20 μm mm to 5 mm, and a width of the voids is ranged from 10 μm to 200 μm, allowing the liquid sample to move from the base end to the tip end due to capillarity.

20220381773 · 2022-12-01 ·

An analytical method for determining a concentration of an analyte is disclosed. In this method, an image of an optical test strip having a body fluid applied thereto is obtained with a camera of a mobile device. Local temperature information is received at a current location of the mobile device from a temperature source such as a remote weather information service or temperature sensor. Additional local temperature information is received by the mobile device from a thermochromic field provided on the test strip and/or on a color reference card. A processor determines a correction temperature and/or a correction temperature function using the local temperature information. The processor also determines the analyte concentration from the image captured and taking into account the correction temperature information.
