AbstractIn this paper we describe the use of a simple and versatile technique of templated electrodeposition through polystyrene sphere templates to produce nanostructured films of gold with regular submicron spherical holes arranged in a hexagonal close-packed structure. The templates were produced by self assembly of a monodispersed suspension of polystyrene spheres on gold substrates using capillary forces. The self assembly process was modified through the chemical modification of the gold substrate with cysteamine thiol. Films of gold were prepared by electrochemical deposition through the template. The electrochemical deposition charge and the current time curve were used to control the film height with a precision of approximately 10 nm. The colour of the nanostructured films changed as the film thickness was changed. Surface enhanced Raman Scattering spectra were recorded and used to identify very low concentrations of aromatic thiol molecules, 4-Nitrobenzenethiol (4-NBT) and 4-Aminobenzenethiol (4-ABT), adsorbed on the surface of the nanostructured gold substrates.
