Abstract

A hydrodynamic approach for assembling a large-area conductive nanomesh of single-walled carbon nanotube (SWNTs) with an exceptional controllability of the nanostructures and with unprecedented material properties was reported. The as-received SWNT solution was dialyzed against a sodium cholate solution for two days with frequent buffer changes. The SWNTs stabilized by the sodium cholate surfactants were then mixed with the p8GB#1 phage in various SWNT:p8GB#1 molar ratios. A mixed solution was placed in a dialysis membrane bag and dialyzed against deionized water. Free-standing SWNT nanomeshes were transferred with pre-patterned stencil masks onto SiO2 heavily doped Si substrates. Transferred nanomeshes were left to air-dry, and the masks were lifted off to produce channels. Then, A 150-nm-thick Au film was sputter-deposited through a stencil mask to define the source and drain electrodes. The biological material controls and stabilizes nanostructures of the conductive nanomesh in the hydrodynamically defined region. The conductive nanomesh exhibits exceptionally controllable nanostructures, excellent electrical properties, and strong adhesion to various types of substrates.
