Title:
DETECTION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/050207
Kind Code:
A1
Abstract:
A detection system, which is applied to the detection of microfluidic chips, which comprises: a detection chip (1), wherein the detection chip (1) comprises a base substrate (11), an electrode layer (12) and a microfluidic channel layer (13) for accommodating a sample solution (B) having magnetic beads (A), the base substrate (11) is provided with a bearing surface, the electrode layer (12) is formed on the bearing surface, the microfluidic channel layer (13) is located on the side of the electrode layer (12) away from the base substrate (11), the electrode layer (12) comprises a plurality of electrodes (121), and the plurality of electrodes (121) have at least one strong magnetic electrode (1211) and a plurality of driving electrodes (1212); a magnetic field device (2), the magnetic field device (2) being located on the side of the base substrate (11) away from the electrode layer (12), and having a strong magnetic region corresponding one to one to the strong magnetic electrode (1211); and a driving mechanism (3), the driving mechanism (3) being connected to the magnetic field device (2), and the driving mechanism (3) driving the magnetic field device (2) to approach or move away from the detection chip (1) in a direction that is perpendicular to the bearing surface. The detection system is used to achieve the automatic separation, purification and enrichment of the sample solution (B) in the detection chip (1).
