Preparation method of surface localized surface plasmon resonance (LSPR)-based molecular imprinting bionic olfaction Ag nano wire sensor

[0025] A method for preparing a molecularly imprinted bionic olfactory Ag nanowire sensor based on surface LSPR, comprising the steps of:

[0026] 1) Pretreatment of aluminum flakes: first soak high-purity aluminum flakes with a thickness of 0.2-0.3mm and a mass purity ≥ 99.99% in acetone for 30 minutes to remove surface oil stains, and then immerse them in 0.1mol / L NaOH solution respectively and 0.1mol / L HCl solution for 20 minutes to dissolve the oxide layer on the surface and polish it; then dry it, put it in a vacuum furnace, and anneal it at 400°C for 4 hours. The purpose of annealing is to eliminate the mechanical stress inside the aluminum sheet and reduce the crystal defects in the lattice, increase the grain size or even eliminate the grain boundary, thereby improving the ordering degree of the template;

[0027] 2) Primary anodizing: the pre-treated aluminum sheet (the aluminum sheet is used as the anode, and the cathode can be a lead plate) is placed in an H-shaped
