Abstract
A apparatus for microfluid detection for detecting a sample fluid including a plurality of magnetic particles is provided. The apparatus for microfluid detection includes a microfluidic chip and a magnetic generating module. The microfluidic chip includes a substrate and microfluidic channels, wherein the sample fluid is carried by a carry surface of the substrate. The magnetic generating module is adapted for providing a positioning magnetic field and a surrounding magnetic field. The magnetic module controls to move the sample fluid and change a distribution of the magnetic particles in the sample fluid through the positioning magnetic field and the surrounding magnetic field.
