PORTABLE PAPER CHIP CAPABLE OF VISUALLY DETECTING CHLORINE ION CONTENT IN SWEAT

摘要

A portable paper-based device capable of visually detecting chlorine ion content in sweat, which is provided with a double-layer structure of paper (3) capable of generating color or fluorescence changes according to pH and anion exchange paper which is arranged on the lower surface of the paper. The paper-based device can be used to visually detect chlorine ion content in sweat. The chloride ion content can be quantified by taking an image of the paper after sufficient contact with the sweat with a digital imaging device, followed by analyzing the color image using an appropriate software or application. The device can be used in monitoring physiological status and diagnosing cystic fibrosis diseases.
