Idea from Mirkin • “DPN is finding applications in certain areas that impact the semiconductor industry such as mask fabrication, inspection and repair…” • “…However, its unique attributes have positioned it on a different path aimed largely at exploiting the properties and applications of nanopatterned soft materials…” -- C. A. Mirkin (2007) Mirkin et al. Nature Nanotechnology 2, 145 (2007).
