DETECTION SYSTEM

A detection system applied to detection of microfluidic chips, includes: a detection chip including a base substrate, an electrode layer and a microfluidic channel layer for accommodating a sample solution having magnetic beads, the base substrate is provided with a bearing surface, the electrode layer is on the bearing surface, the microfluidic channel layer is on the side of the electrode layer away from the base substrate, the electrode layer includes electrodes including at least one strong magnetic electrode and driving electrodes; a magnetic field device being on the side of the base substrate away from the electrode layer, and having a strong magnetic region corresponding one to one to the strong magnetic electrode; a driving mechanism being connected to the magnetic field device, and driving the magnetic field device to approach or move away from the detection chip in a direction that is perpendicular to the bearing surface.
