Self-assembled electrical circuit made from DNA modified carbon nanotubes
A straightforward two-step method for the self-assembly of single-walled
carbon nanotubes (SWNTs) between gold electrodes is presented.
The technique utilizes the hybridization between short complementary DNA
sequences located on metal contacts and SWNTs. The new technique enables
simple production of hundreds of devices with high yields. The
electrical characteristics are shown to depend strongly on the existence
of the chemical binding group and are controlled by the transport
through these groups.
