Abstract
Disclosed are a molecule detection unit, a chip and a preparation method. The molecule detection unit includes 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. The first structural layer is arranged on the 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, and 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 the top of the first structural layer and covers the top of the buffer flow channel.
