Electrochemical tongs for developing protein molecule electronic device and method for producing the same

Abstract

The invention relates to a pair of electrochemical pliers used for developing a protein molecule electronic device and a fabricating method thereof. The fabricating method is characterized in that the surface of an insulating basal material is uniformly coated with an inner layer and an outer layer of annular conductors of nanometer-level thickness, and a nanometer isolating layer of adjustable thickness is used for isolation. The annular conductors of the inner layer and the outer layer are respectively supplied with proper voltage, and electrostatic attracting force is used for clamping protein molecules causing the protein molecules to be arranged in parallel in a fixed direction; an outer circuit is used for supplying an activating signal to the protein molecules clamped by the electrochemical pliers; the relationship between an input signal and an output signal is analyzed to obtain the inner electronic transferring system of the protein molecules and develop the electronic device of the protein molecules. The electrochemical pliers provided by the invention has light action force, the shape and the quality of the protein can not easily change, touched molecule number is high, the signal is strong, the surface regeneration is easy, the used instrument is simple, the information is on-site, and the scanning speed is high. The fabricating method can be used for developing the electronic device of the protein molecules, particularly the electronic device of the protein molecules with high-speed response ability.

Description

technical field [0001] The invention relates to the technical fields of electroanalytical chemistry, molecular electronic devices, and biosensors, in particular to a structure and a manufacturing method of an electrochemical clamp that can be used for developing protein molecular electronic devices. Background technique [0002] The development trend of large-scale and ultra-large-scale integrated circuits is to continuously reduce the size of electronic devices, and has now entered the era of nanoelectronic devices. At present, there are two main ways to develop nanoelectronic devices: one is to use microelectronic processing technology to further reduce the size of traditional electronic devices, but when approaching or reaching the nanometer scale, quantum mechanical effects and thermodynamic statistical fluctuation effects gradually make the development of contemporary microelectronics are severely restricted; the second is the development of molecular electronic devices...
