Electrical Characterization of DNA Origami Nanostructure

DNA origami method provides programmable bottom up approach for developing of any desired shaped structures from nanoscale components and with the help of the hybridization formation of the functional nanostructures can be controllable by DNA origami nanostructure. One of the goals to design tailored bottom up based nanophotonics, optoelectronics and nanoelectronics devices based on DNA functionalization such as metallization or controlled attachment of nanoparticles to the DNA origami design. However, combination of bottom-up and top-down based methods is required for future nanoelectronic device applications. In this study, gold nanoparticles are decorated on DNA origami accumulated to SiO2 surface utilized for molecular electronics. For this novel approach, we combined bottom-up and top-down based methods, two metallic electrodes contacted on individual gold nanoparticles decorated DNA origami nanotube by electron beam lithography. The charge transport behavior of the molecule between gold nanoparticles occurs in temperature range from room temperature to 4.2 K.
