Abstract
A microfluidic chip for analyte detection, which is provided with a liquid storage tank (), the liquid storage tank () is internally provided with a through hole I (), one opening of the through hole I is located in the liquid storage tank, and the liquid in the liquid storage tank passes through the through hole I to bypass the outer boundary () of the portion where the inner surface of the liquid storage tank contacts the sealing member, thereby avoiding leakage due to a possible gap in a sealed position when the liquid flows through the sealed position. At the same time, the design can reduce the processing precision requirement, save cost, etc.
