Abstract
A multi-waveband-tunable multi-scale meta-material and a preparation method and a spectral detection method thereof are provided. The meta-material includes a stretchable layer, a non-stretchable support layer, a metal layer, and a nanoparticle layer sequentially stacked from bottom to top. The stretchable layer is a polydimethylsiloxane (PDMS) layer. The non-stretchable support layer is a polyimide (PI) layer. The metal layer is a gold layer. The nanoparticle layer is modified with a hydrophobic group. The preparation method includes vacuum-evaporating fluorosilane on a silicon wafer, spin-coating PDMS, heat-curing PDMS, conducting plasma cleaning, spin-coating and curing PI, sputtering gold, self-assembling the nanoparticles on a water surface to form the nanoparticle layer, transferring the nanoparticle layer to the metal layer, and etching according to a pattern. The multi-waveband-tunable multi-scale meta-material can sense biochemical molecules by utilizing the advantages of multiple wavebands, is simple and fast to operate, and is suitable for various detection needs.
