Reusable Stamps for Printing Sub-100 nm Patterns of Functional Nanoparticles

The production of reusable stamps for the creation of high-resolution patterns of functional nanoparticles is demonstrated. A patterned stamp is cleaned by removing nanoparticles in the recessed regions of the stamp, using a UV-curable adhesive, before moving on to the next cycle of printing with the stamp. A high-resolution patterning technique using rigid stamps with a low surface energy and the repeated use of the reusable stamps for defining sub-100 nm scale features is demonstrated. Color patterning has also been performed using just one color per stamp, then by the use of one stamp for multiple colors. © 2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
