ABSTRACT:
The methods and apparatus disclosed herein concern nanoparticle layers uniformly distributed on a surface or substrate. In certain embodiments of the invention, the nanoparticle layers are of use for Raman spectroscopy. In certain embodiments of the invention, a micelle-metal ion complex is formed and deposited on a surface. The polymer component of the micelle-metal ion complex may be removed resulting in formation of nanoparticles of a uniform size and distribution. The polymers may contain one or more ligands. The number and type of ligands in a micelle will determine the type and amount of metal ion bound to the micelle, in turn determining the metal composition and size of the nanoparticles. The distribution micelle-metal ion complexes on a surface may determine the distribution and periodicity of the nanoparticle layer. In other embodiments, rod or columnar-shaped nanoparticles may be generated. Other embodiments concern the generation of uniform alloy nanoparticles.
