Embodiment 1

[0026] In the first step, the large blue morpho butterfly wing is placed in a 6wt% HCl solution for 24 hours to dissolve the minerals that are not easily removed by sintering, and then rinse with distilled water. Then put it into a 10wt% NaOH solution and treat it at 60°C for 3 hours to dissolve most of the chitin. After taking out the butterfly wings treated in this way, rinse them with distilled water and dry them for later use.

[0027] The second step is the preparation of the precursor solution. The preparation scheme of the tetraethylorthosilicate solution: anhydrous ethanol, water, and tetraethylorthosilicate at a molar concentration ratio of 3:12:1 are mixed and stirred to prepare a precursor solution.

[0028] In the third step, the processed butterfly wings are put into the prepared precursor solution for ultrasonic treatment, the ultrasonic power is 300W, and the ultrasonic time is 2.5 hours.

[0029] In the fourth step, after the ultrasound, the sample is taken out, rin...

Abstract

The invention discloses a method for preparing conducting polymer with a butterfly wing photonic crystal structure in the technical field of biosensors. A butterfly wing multilayer and multi-dimensional fine structure is taken as a template, and a SiO2 porous material with a butterfly wing fine structure is prepared to serve as a secondary template through surface treatment and chemical modification according to different chemical reactivity of bio-chemical components by permeation, sol-gel and ultrasonic methods; and polymer is further assembled into the fine structure of the SiO2 porous material, and the conducting high polymer material with the butterfly wing photonic crystal structure is prepared by controlling chemical reaction in the SiO2 template through manual coupling. The invention creatively utilizes a secondary template technology, and synthesizes the conducting high polymer material with the photonic crystal structure; and the photonic crystal structure greatly improves the response of the conducting high polymer to biomolecules, so that the conducting polymer has wide application prospect in the field of biosensors.

Description

Technical field [0001] The invention relates to a method in the technical field of biological sensing, in particular to a method for preparing a conductive polymer with a butterfly wing photonic crystal structure. Background technique [0002] The bionic construction of biological fine structure can not only combine the multi-dimensional, multi-structure and multi-component hierarchical fine structure of organisms with the optical, electrical, and magnetic properties of functional materials, but more importantly, through the non-functional properties of organisms. The coupling effect of special structures and functional materials that can be synthesized artificially can obtain new structural materials with greatly improved performance. Butterfly wing is just such a typical example of using its own hierarchical fine structure to achieve various excellent performance. Butterfly wings have arguably the most exquisite and complex microstructure among biological structures. These but...
