Researchers made the smallest diode using a DNA molecule
A team of researchers from the University of Georgia and Ben-Gurion University has developed an electronic component so tiny, you can't even see it under an ordinary microscope. See, the team used a single DNA molecule to create a diode, a component that conducts electricity mostly in one direction. Further, the DNA molecule they designed for the study only has 11 base pairs. That makes it a pretty short helix, considering a human genome has approximately 3 billion pairs.
