Embodiment

[0017] A method for making a gold nanoarray, comprising the steps of:

[0018] 2) The design of the positioning template, through the design of the template, determine the size and quantity of the micro-area, each micro-area must be an independent area;

[0019] 2) According to the number and size of the designed templates in step 1), use a laser direct writing machine to make a template mask, and then select a glass sheet as the substrate material, and deposit the cleaned glass sheet through high vacuum resistance evaporation on it. Deposit a chrome layer with a thickness of 250-300 nm on the surface; make the designed pattern on the glass substrate by photolithography, and edit the number;

[0020] 3) Put the prepared positioning template in step 2) into the washing solution made of concentrated sulfuric acid and hydrogen peroxide. The ratio of concentrated sulfuric acid and hydrogen peroxide is 3:1, heat to 80°C, and soak for 60 minutes;

[0021] 4) Rinse the positioning t...

Abstract

The invention provides a method for making a gold nanoarray, which is easy to operate, realizes the array of local surface plasmon structures, and can also fill different units with nanosphere structures of different sizes, which is a simple and effective method. Nano-metal structure processing means, the gold nano-array structure produced by this method has the characteristics of low defect, high specific surface area and structural order. Sensitive biosensing provides an effective means.

Description

technical field [0001] The invention belongs to the field of nanometer materials, in particular to a method for manufacturing a gold nanometer array. Background technique [0002] In recent years, with the development of microfabrication technology and nano-materials, more and more attention has been paid to the electromagnetic properties of nano-metal structures. The interaction between light and nano-metal structures has produced a series of new physical phenomena. When the electromagnetic wave is incident on the surface of the nano-metal array structure, the local surface plasmon generated can greatly enhance and concentrate the electromagnetic energy. Based on these characteristics, the nano-metal structure is used in biosensing, chemical sensing, optical design and magnetic It has broad application prospects in data storage and other fields. [0003] Biosensors based on this principle have faster detection speed and sensitivity than traditional biosensors in the labeli...
