METHOD AND A SYSTEM FOR QUANTITATIVE OR QUALITATIVE DETERMINATION OF A TARGET COMPONENT

摘要

A method and a system for quantitative or qualitative determination of a target component in a liquid sample. The method includes i) providing a plurality of magnetic particles including capture sites for the target component on their respective surfaces; ii) providing a plurality of fluorophores configured to bind to the capture sites of the magnetic particles; iii) bringing the liquid sample into contact with the fluorophores and the magnetic particles in a flow channel of a micro fluidic device including a transparent window; and iv) at least temporally immobilizing the magnetic particles adjacent to the transparent window using a magnet, emitting exciting electromagnetic beam towards the immobilized magnetic particles, reading signals emitted from fluorophores and performing a quantitative or qualitative determination of the target component based on the read signal. A suitable micro fluidic device for use in the method/system and a kit for preparing a liquid sample.
