Claim 0:
1. A digital immunochip, comprising a first substrate and a second substrate opposite to each other; wherein
the first substrate comprises:
a first base substrate;
at least one driving electrode on the first base substrate and configured to drive an object to be detected to move;
a dielectric layer on a side of the at least one driving electrode away from the first base substrate and covering the at least one driving electrode, and
a first hydrophobic layer on a side of the dielectric layer away from the first base substrate; and
the second substrate comprises:
a second base substrate; and
an immunoassay substance on a side of the second base substrate proximal to the first hydrophobic layer of the first substrate and comprising an antigen or an antibody
the second substrate further comprises:
a second hydrophobic layer between the immunoassay substance and the second base substrate and having a plurality of via holes exposing a lower surface of the second base substrate, and
a plurality of sample portions filled in plurality of via holes formed in the second hydrophobic layer and configured to carry the immunoassay substance thereon, wherein
a surface of the second hydrophobic layer proximal to the first substrate is a flat surface, surfaces of the plurality of sample portions proximal to the first substrate are flat surfaces, and the surface of the second hydrophobic layer proximal to the first substrate is on the same plane as the surfaces of the plurality of sample portions proximal to the first substrate, and
the plurality of sample portions have a thickness the same as a thickness of the second hydrophobic layer.
