Abstract
A medical detection substrate and a manufacturing method thereof, a medical detection chip and a medical detection system are provided. The medical detection substrate includes: a substrate, and a detection unit on the substrate; the detection unit includes two groups of test electrodes, the substrate includes a plurality of recessed portions, and the at least two groups of test electrodes are located in the plurality of recessed portions and spaced apart by insulation bank portions. The two groups of test electrodes are insulated and spaced apart by the insulation bank portions, so as to effectively avoid a transverse interference electric field to be generated between the two groups of test electrodes, thereby effectively improving the detection accuracy and sensitivity of the medical detection substrate, and providing a reliable basis for disease diagnosis.
