Electronic devices will be able to repair themselves thanks to DNA

The team used two strands of DNA. One contained 10 nucleotides (the main component of DNA is Hi-Tech),

and in the second - 90.From each, the researchers formed a structure similar to lightning, and then attached it to a gold surface and to the metal tip of a tunneling microscope (a device used to study surfaces at the atomic level - Hi-Tech).

“We have investigated the transfer of electrons throughsingle-molecule transition of DNA-lightning, which is located perpendicular to the axis of the “nanogap” between two metals. This transition differs from the usual not only in the configuration of the DNA, but also in the location, ”explained Dr. Tomoaki Nishino of the Tokyo Institute of Technology.

The team found that the single-molecule transitionwith long DNA shows much higher conductivity. Modeling of the process has shown that this may be due to delocalized π-electrons, which freely move in the molecule. Scientists also saw that a single-molecule transition can restore itself after an electrical failure, as if moving from the state of an open zipper to a buttoned one.

The team is confident that their research will help indevelopment of future technologies. It could become the basis for innovations in nanoscale electronics, which in turn will revolutionize nanobiotechnology, medicine and related fields.
