MICROFLUIDIC SYSTEM, CARTRIDGE AND METHOD FOR PREPARING SAMPLE

摘要

A microfluidic system for preparing a sample containing an analyte of interest is provided. The microfluidic system includes a microfluidic cartridge and a magnetic element. The microfluidic cartridge includes a number of reservoirs, an immobilizer, a number of microfluidic flow channels and a number of microvalves. The microfluidic channels are coupled with the reservoirs and the immobilizer. The microvalves are positioned along the microfluidic flow channels. The magnetic element is positioned with respect to the immobilizer. The magnetic element is configured to generate a magnetic field to magnetically immobilize the analyte of interest in the immobilizer. The immobilizer is configured to flow one or more reagents therethrough to react with the analyte of interest.
