[0028] (1) Synthesis of gold nanorods

[0029] Gold nanorods with an aspect ratio of about 3.0 were synthesized according to the method of the patent "A Preparation Method of Self-Assembled Materials with Surface-Enhanced Raman Activity" (Patent No.: ZL 201010605799.9). The simple steps are as follows:

[0030] ① Seed crystal synthesis: Add 0.1mL of pre-configured 2g / L tetrachloroauric acid trihydrate to 1mL of 0.2M cetyltrimethylammonium bromide solution at 28.0°C. At this time, the color of the solution From colorless to yellowish brown. Then, 0.12 mL of newly prepared 0.01 M sodium borohydride solution was added to the above mixed system and stirred rapidly for 2 min. The color of the solution changed from yellowish brown to light brown. Put the above-mentioned synthesized seed crystal into a water bath at 28.0°C and let it stand for 30 minutes to react, so that the sodium borohydride that does not fully participate in the synthesis of the seed crystal is completely cons...

Abstract

The invention provides a preparing method of a high conductivity chain-shaped photoelectric nanometer bridge and belongs to the technical field of material chemistry. The end surface regional functional technology of gold nanorods is used, the surface modification of oligonucleotide is realized to the designated region of the gold nanorods, and the chain-shaped structure of the nanorods is formed by means of the bionic identifying nature of the oligonucleotide; the nanometer photoelectric nanometer bridge of the nanorods is realized by regulating the conditions of the position of electrodes, the electric potential, the buffering medium and the like, so that two unconnected conductors can be powered on, a nanometer electric wire is obtained, and the conducting efficiency is effectively improved.

Description

technical field [0001] The invention relates to a preparation method of a chain photoelectric nano bridge with high conductivity, belonging to the technical field of material chemistry. Background technique [0002] Nanomaterials refer to materials whose three-dimensional spatial scale has at least one dimension at the nanometer level. Nanomaterials are a new generation of materials between atomic clusters and macroscopic materials. Since the size of nanomaterials is close to the de Broglie wavelength of electrons, the superconducting coherence wavelength, and the Bohr radius of excitons, electrons are confined to a very small space, and their wave functions are limited. In addition, they have a large surface area. Therefore, nanomaterials show novel optical, electrical, magnetic and chemical properties different from conventional bulk materials. The assembly of nanomaterials will have new optical, electrical, magnetic and catalytic properties based on the properties of in...
