  • Paper-based colorimetric sensor kit for quickly and simply diagnosing mercury in situ with naked eye and method for quickly and simply detecting mercury in situ with naked eye using the same
    Patent number: 11519023
    Abstract: There is provided a paper-based colorimetric sensor kit for quickly and simply diagnosing mercury in situ with a naked eye. The paper-based colorimetric sensor kit includes: a circular template for rolling circle amplification (RCA); a primer that does not hybridize to the circular template when a mercury ion is bonded to a primer that hybridizes to the circular template; a DNA polymerase; a sensing material kit including a nanoparticle probe labeled to a DNA coil formed in the circular template for RCA; and a radial chromatography paper.
    Type: Grant
    Filed: December 27, 2018
    Date of Patent: December 6, 2022
    Assignee: KOREA FOOD RESEARCH INSTITUTE
    Inventors: Min-Ah Woo, Min-Cheol Lim, Sung-Wook Choi, Tai-Yong Kim
