Abstract
A method for diagnosing a biomarker using magnetic particles and quantum dots for quantitative analysis and a biomarker diagnosis kit are provided. The method for diagnosing a biomarker includes: ii) providing magnetic particles having surfaces to which a primary antibody capable of collecting a biomarker using a linker is fixed; ii) providing quantum dots having surfaces to which a secondary antibody capable of detecting the biomarker is fixed; iii) sandwich-targeting the biomarker by the magnetic particles and the quantum dots; iv) selectively separating quantum dots sandwich-targeting the biomarker among the quantum dots; and v) quantifying the concentration of the biomarker by measuring absorbance or intensity of fluorescence of separated quantum dots.
