Nucleic Acids nanotechnology is currently being developed as a general self-assembly method for nanopatterned materials that may find use in electronics, sensor, medicine, and many other fields.
Presented in this talk include 1) self assembly of DNA nanotube, DNA origami (rectangle-hole), and DNA nanotriangle, 2) metallization of DNA nanotube, and 3) on-surface RNA mediated nanoparticle synthesis.
The construction principal of DNA nanotube, DNA origami, and DNA nanotriangle, high resolution atomic force microscopy (AFM) images of these DNA nanostructures, experimental evidence of the DNA tube-like nature as well as data on metallization of the nanotube to form nanowires, and electrical conductivity measurements through the nanowires will be presented. RNA codes that can catalyze the synthesis of hexagonal microcontact printing and their on-surface catalysis activities were characterized. When coupled to gold via oligoethylene glycol linkers, both RNA sequences were able to catalyze the formation of Pd particles with the same shape control as previously observed in solution.
