  • Universal matrix
    Patent number: 8084273
    Abstract: The application relates to a method of depositing a patterning species from a nanoscopic tip to a substrate surface. The method is carried out at a sufficiently high humidity to facilitate the deposition. The deposition of the patterning species is facilitated by a polysaccharide carrier as well as an additional additive.

  • UNIVERSAL MATRIX
    Publication number: 20100048427
    Abstract: A method comprises: (i) providing a tip and a substrate surface, (ii) disposing a patterning composition at the end of the tip, (iii) depositing at least some of the patterning composition from the tip to the substrate surface to form a deposit disposed on the substrate surface, wherein the patterning composition comprises at least one patterning species, at least one carrier that is different from the patterning species, and at least one additive different from the patterning species and the carrier.
