Sub-10 nm Patterning with DNA Nanostructures: A Short Perspective


DNA is the hereditary material that contains our unique genetic code. Since the first demonstration of two-dimensional (2D) nanopatterns by using designed DNA origami ~10 years ago, DNA has evolved into a novel technique for 2D and 3D nanopatterning. It is now being used as a template for the creation of sub-10 nm structures via either top-down or bottom-up approaches for various applications spanning from nanoelectronics, plasmonic sensing, and nanophotonics. The perspective starts with an historic overview and discusses the current state-of-the-art in DNA nanolithography. Emphasis is put on the challenges and prospects of DNA nanolithography as the next generation nanomanufacturing technique.
