title: Polymerized nanotips via two-photon photopolymerization.
abstract: We present new methods to produce polymerized nanotips via two-photon photopolymerization. By gradually changing the laser power, we fabricate a single polymerized tip with the size of 120nm. When two rectangle anchors with protuberances are close enough, lines with the slimmest part of about 20-30nm and tips with the widths of about 35nm are produced between anchors, which are the best resolution obtained with the resin SCR-500 to our knowledge. As the tips are adhered to larger polymerized structures, they can survive post processing in spite of their small sizes.
