Abstract

The invention provides an electrochemical detection device based on a self-assembling technology and a micro-fluidic chip technology. A sample injection system comprises a sample feeder and a micro-fluidic chip. The micro-fluidic chip comprises a sample inlet, and a sample channel, an antibody channel and a detection liquid channel which are communicated with the sample inlet. Control valves are arranged on the sample channel, the antibody channel and the detection liquid channel, and the sample feeder is connected with the sample inlet. Storage systems are respectively arranged on the antibody channel and the detection liquid channel. Driving systems are arranged on the storage systems. A detection system comprises an electrode group and an electrochemical detector connected with the electrode group, and the micro-fluidic chip is connected with the electrode group. A working electrode in the electrode group is coated with a first antibody corresponding to a sample, a freeze-dried second antibody corresponding to the sample is placed in the antibody channel, and the storage systems respectively store a second antibody dissolving solution and a detection solution. The device reducesuse of human resources, reduces the detection cost, greatly increases the detection efficiency, and realizes high-throughput detection.

Description

technical field [0001] The invention relates to the technical field of electrochemical detection, in particular to an electrochemical detection device based on self-assembly technology and microfluidic chip technology. Background technique [0002] Molecular self-assembly technology refers to the process in which molecules spontaneously form molecular assemblies with special structures and shapes under the impetus of weak forces such as hydrogen bonds, electrostatics, van der Waals forces, and hydrophobic and lipophilic forces. This technology provides people with a new method to effectively construct various structural systems from the molecular level. The self-assembly technology realized by the principle of self-assembly is spontaneous in situ, thermodynamically stable, simple in composition and independent of substrates. The influence of the shape of the material can form many advantages such as uniformity and stability, orderly arrangement of molecules, low defects, and...
