1. A method of depositing a nanoscale-thin film in a preselected area on a substrate, the method comprising:
depositing a layer of a functionalizing molecule onto or adjacent to a first surface of the substrate;
functionalizing the first surface of the substrate by focusing a source of ionizing radiation onto the layer of the functionalizing molecule to create a desired pattern of functionality with nano-scale spatial resolution on the substrate;
removing the layer of the functionalizing molecule; and
depositing a nanoscale-thin film onto the functionalized first surface of the substrate to form a deposited nanoscale-thin film.
