In every advanced organism, DNA (deoxyribonucleic acid) molecules constitute the genetic code

Researchers from Japan made some suggestions in a new breakthrough study

How did researchers achieve this achievement? Dr.

The research team used a 10-mer and a 90-mer (representing the number of nucleotides that make up the length of the molecule) of DNA to form a zipper-like structure and attach it to the gold surface or the metal of a scanning tunneling microscope.

By measuring an amount called "tunneling current" that passes through the nanogap, the team estimated the conductivity of the DNA connection relative to a bare nanogap without DNA

To their delight, they found that single-molecule knots of 90-mer DNA exhibited unprecedented high conductivity

After these findings, the team is excited about their future technological development

In fact, this is an exciting time in the field of molecular electronics!
