Abstract
The disclosure relates to methods of printing indicia on a substrate using a tip array comprised of elastomeric, compressible 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.

- 29. A tip array comprising a plurality of tips fixed to a common substrate layer, the tips and common substrate layer formed from an elastomeric polymer, the elastomeric polymer of the tips having a compression modulus of about 10 MPa to about 300 MPa, and each tip having a radius of curvature of less than about 1 μ

43. 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 prepolymer mixture comprising an prepolymer and, optionally, a crosslinker; curing the prepolymer mixture to form a polymer structure; and separating the polymer structure from the master. - View Dependent Claims (44, 45)
