Abstract
The disclosure relates to methods of printing indicia on a substrate using a tip array comprised of elastomeric, compressible gel polymers. The tip array can be prepared using conventional photolithographic methods and can be tailored to have any desired number and/or arrangement of tips. Numerous copies (e.g., greater than 15,000, or greater than 11 million) of a pattern can be made in a parallel fashion in as little as 40 minutes.

41. A method of making a tip array, comprising:
-
forming a master comprising an array of recesses in a substrate separated by lands; filling the recesses and covering the lands with a polymer gel mixture comprising a polymer gel material dispersed or dissolved in a solvent and, optionally, a buffer solution; curing the polymer gel solution to form a polymer gel structure; and separating the polymer gel structure from the master. - View Dependent Claims (42, 43, 44, 45, 46)
