|Scientists have announced a significant breakthrough toward developing DNA-based electrical circuits. Molecular electronics, which uses molecules as building blocks for the fabrication of electronic components, has been seen as the ultimate solution to overcoming the limits of Moore's Law.|
In new research published in Nature Nanotechnology, an international group of scientists has announced the most significant breakthrough in a decade toward developing DNA-based electrical circuits.
The central technological revolution of the 20th century was the development of computers, leading to the communication and Internet era. The main measure of this evolution is miniaturization: making our machines smaller.
"This research paves the way for implementing DNA-based programmable circuits for molecular electronics, which could lead to a new generation of computer circuits that can be more sophisticated, cheaper and simpler to make."
Now, an international group led by Professor Danny Porath, the Etta and Paul Schankerman Professor in Molecular Biomedicine at the Hebrew University of Jerusalem, reports reproducible and quantitative measurements of electricity flow through long molecules made of four DNA strands, signaling a significant breakthrough towards the development of DNA-based electrical circuits. The research, which could re-ignite interest in the use of DNA-based wires and devices in the development of programmable circuits, appears in the prestigious journal Nature Nanotechnology under the title "Long-range charge transport in single G-quadruplex DNA molecules."
According to Porath, "This research paves the way for implementing DNA-based programmable circuits for molecular electronics, which could lead to a new generation of computer circuits that can be more sophisticated, cheaper and simpler to make."
