Abstract:
1. A method comprising: providing a nanoscopic tip and a substrate surface, disposing a patterning composition at the end of the tip, contacting the tip with the substrate surface, thereby transferring 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 transfer is carried out at a relative humidity sufficiently high so that the transfer occurs, wherein the patterning composition comprises at least one patterning species, at least one carrier that is different from the patterning species and comprising polysaccharide, and at least one additive comprising a molecule different from the patterning species and the carrier, wherein the polysaccharide dominates the rate of deposition of the patterning species, and wherein the additive activates or increases the rate of deposition of the polysaccharide and the patterning species, and wherein the patterning species comprises a molecule which is to be deposited.
