Nanostructures of Cysteine-Coated CdS Nanoparticles Produced with “Two-Particle” Lithography

Abstract

There is an emerging need for practical methods that can produce organized arrays of nanomaterials with high throughput. Particle lithography provides such an approach for rapidly preparing millions of exquisitely uniform nanometer-sized structures on flat surfaces, using basic steps of bench chemistry. Structural templates of monodisperse latex or silica mesospheres can guide the deposition of nanoparticles to generate 2D arrays of nanopatterns with control of the surface coverage, size, and periodicity of nanoparticle structures.
