Abstract
The present invention relates to methods of making nanoarrays for use in detecting species formed on the surface of the array using SE(R)RS. The methods can involve nanolithographic printing of a compound by dip pen nanolithographic printing. A SE(R)RS substrate can be used for the array and which can be selected from surfaces roughened by the oxidation-reduction cycle (ORC), island films, colloidal nanoparticles and surface-confined nanostructures. A coating or intermediate layer, such as a layer formed of nitrocellulose, can be provided between the compound and the SE(R)RS substrate. There are also provided arrays themselves and methods of using such arrays.
