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.
