    摘要: An improved method of loading tips and other surfaces with patterning compositions or inks for use in deposition. A method of patterning is described, the method comprising: (i) providing at least one array of tips; (ii) providing a plurality of patterning compositions; (iii) ink jet printing at least some of the patterning compositions onto some of the tips; and (iv) depositing at least some of the patterning compositions onto a substrate surface; wherein the ink jet printing is adapted to prevent substantial cross-contamination of the patterning composition on the tips. Good printing reproducibility and control of printing rate can be achieved. The surfaces subjected to ink jet printing can be treated to encourage localization of the ink at the tip. The method is particularly important for high density arrays.

    摘要: 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.
