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.
