| titleOfInvention | A kind of preparation method of macroscopic size close-packed gold nanoparticle monolayer film |
| abstract | A method for preparing a macro-sized close-packed gold nanoparticle monolayer film. First, an oily solvent is used to configure amines into an amine-containing oily solution with a molar concentration of 0.0001-0.1 mol/L; then 16-nanometer gold nanoparticles are used as seeds, and use the seed growth method to prepare a gold nanoparticle sol with a size range of 30-150 nanometers; then mix the gold nanoparticle sol with the amine-containing oily solution in a volume ratio of 5:1-3, let stand, and wait for the upper layer When the oil phase is completely volatilized, the macro-sized gold-based self-assembled monolayer close-packed nanomembrane is obtained; finally, the membrane is completely taken out with a glass sheet treated with acid and alkali, and the surface is rinsed with ethanol and dried in a vacuum or nitrogen atmosphere. The invention is simple to operate, can obtain single-layer, high-quality, close-packed, macro-sized single-layer films of close-packed gold nanoparticles that can be used as Raman-enhanced substrates, and has uniform surface-enhanced Raman scattering properties, thereby realizing them Quantitative detection in the field of Raman enhancement. |
