Abstract

Dense two-dimensional assemblies of silver nanoparticles were fabricated over vast areas (∼19 cm2) by utilizing a simple liquid–liquid interface assembly technique. The Raman signal for p-aminothiophenol immobilized on the assemblies was drastically enhanced by plasmon coupling-induced hot spots, and the enhanced signal showed high spatial reproducibility.
