Summary: This project will investigate the properties of gold nanoparticles and their interactions with adsorbed molecules under the influence of light irradiation. The aim is to develop a novel lithographic method for patterning substrates with nanometer resolution. The strong absorption of gold nanoparticles at visible wavelengths will provide the patterning mechanism by modifying an underlying film following irradation by visible light. With this process the conventional diffraction limit of optical lithography can be circumvented providing a relatively cheap, and easy approach to nanoscale lithography.
