    Abstract: A novel method of transporting ink to a substrate with dip-pen nanolithographic (DPN) stamp tips coated with polymer (e.g., polydimethylsiloxane (PDMS), etc.). This kind of tip adsorbs chemicals (“inks”) easily and is used to generate DPN nanopatterns that are imaged with the same tip after a DPN process. This method builds a bridge between micro-contact printing (μCP) and DPN, making it possible for one to easily generate smaller structures of any molecules that have been patterned by the μCP technique. The easy tip-coating and writing process enriches the state-of-the-art DPN technique. The sub-100 nm DPN resolution obtained by using this kind of novel tip is comparable to that with a conventional Si3N4 probe tip. Importantly, the unique stamp tip was able to transfer solvent (e.g., liquid “ink”) onto a substrate, resulting in fabrication of hollow nanostructures with only one DPN holding/writing step. Inks comprising metals and sol-gel materials are noted, as well as applications in photomask repair, enhancement, and fabrication.

    Abstract: The use of direct-write nanolithography to generate anchored, nanoscale patterns of nucleic acid on different substrates is described, including electrically conductive and insulating substrates. Modification of nucleic acid, including oligonucleotides, with reactive groups such as thiol groups provides for patterning with use of appropriate scanning probe microscopic tips under appropriate conditions. The reactive groups provide for chemisorption or covalent bonding to the substrate surface. The resulting nucleic acid features, which exhibit good stability, can be hybridized with complementary nucleic acids and probed accordingly with use of, for example, nanoparticles functionalized with nucleic acids. Patterning can be controlled by selection of tip treatment, relative humidity, and nucleic acid structure.
