Claim 0:
1. A molecular detection unit, comprising: a single-hole liquid storage cavity, a liquid resistance flow channel, a buffer flow channel, a sensing electrode, a substrate, a first structural layer, a second structural layer, and a sample flow channel; wherein
the first structural layer is arranged on a top of the substrate;
the single-hole liquid storage cavity and the buffer flow channel are arranged in the first structural layer and are independent of each other;
the liquid resistance flow channel is arranged in the first structural layer; two ends of the liquid resistance flow channel are respectively communicated with the single-hole liquid storage cavity and the buffer flow channel;
the second structural layer is arranged on a top of the first structural layer and covers a top of the buffer flow channel;
the sample flow channel is communicated with the single-hole liquid storage cavity; and
the sensing electrode is arranged in the substrate; one end of the sensing electrode is connected to the single-hole liquid storage cavity for detecting a voltage applied to a side of the single-hole liquid storage cavity.
