Claim Text:
1. An apparatus for microfluid detection, adapted to detect a sample fluid comprising a plurality of magnetic particles, the apparatus for microfluid detection comprising: a microfluidic chip, comprising a substrate and microfluidic channels formed on the substrate, wherein the sample fluid is carried by a carry surface of the substrate; and a magnetic generating module, comprising a ring-shape hollow magnetic generating module and a surrounding magnetic generating module, wherein the ring-shape hollow magnetic generating module is disposed on at least one side of the carry surface, and the ring-shape hollow magnetic generating module is adapted to provide a positioning magnetic field to the sample fluid, the surrounding magnetic generating module is disposed at periphery of the microfluidic chip, and the surrounding magnetic generating module is adapted to provide a surrounding magnetic field to the sample fluid, wherein the magnetic generating 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.
