PAPER-BASED COLORIMTRIC SENSOR FOR HIGH EFFICIENT RAPID AND VISUAL DETECTION OF BACTERIAL PATHOGEN AND HIGH EFFICIENT RAPID AND VISUAL DETECTION OF BACTERIAL PATHOGEN

摘要

Provided is a paper-based colorimetric sensor kit for a rapid and simple naked eye diagnosis of pathogenic bacteria. The paper-based colorimetric sensor kit comprises: a complex conjugate solution where aptamers, capable of selectively binding to target bacteria and DNAzyme, are bound to a magnetic nanoparticle having enzyme-like action; a substrate causing a colorimetric reaction by the magnetic nanoparticle having the enzyme-like action and enzymatic action of the DNAzyme; and radial paper chromatography on which the complex conjugate and the substrate reacted with a test sample are provided on a surface and a colorimetric ring is formed when the target bacteria are in the test sample.
