Dip-Pen Nanolithography Dip-Pen Nanolithography DPN)is an AFM lithography technique where molecules are transported from AFM tip to surface to form nanostructures AFM Tip Water meniscus spontaneously condenses between AFM tip and surface, which facilitates transport of the molecules fron tip to surface. Deposition occurs due to Au subway surface affinity of the solutes. From Piner et al. Science 283 661. Previous efforts(by Chad Mirkin, NWU) serial patterning of alkanethiols on gold parallel patterning using several AFM tips patterning alkanethiol-based etch resists Patterning hexamethy ldithilathane on semiconductor surfaces
