Abstract
The invention provides a lithographic method referred to as 'dip pen' nanolithography (DPN). The method include the following steps: (i) providing a substrate and a scanning probe microscope tip; (ii) coating the tip with a patterning compound and a solvent to form a wet tip; and (iii) contacting the coated tip with the substrate so that the compound is applied to the substrate so as to produce a desired pattern. The invention also provides substrates patterned by DPN and kits for performing DPN.
