Cortisol measurement kit


Currently, cortisol level measurements in the body performed in laboratories typically use the Electrochemiluminescence Immunoassay (ECLIA) method, which requires expensive materials, equipment, and specialized personnel. Researchers have developed a cortisol measurement kit that uses paper as a substrate, which is more cost-effective, and wax ink to delineate the testing area, allowing for customizable test areas. The design features a small test area to reduce the amount of samples needed. This kit still relies on the competitive immunoassay principle and utilizes gold nanoparticles (AuNPs) as signal indicators, which produce a visible color change that can be observed with the naked eye. This makes the kit easy to use, convenient, and applicable for measuring cortisol levels in the body.
