To allow a current to flow through the DNA, the team inserted a molecule called "coralyne" into the helix. What the team came up with was a diode, because the current was 15 times stronger for negative voltages than for positive. The study's lead author Bingqian Xu decided to experiment on DNA to create minuscule components, since we can't exactly use silicon for parts that size.

He said:

"For 50 years, we have been able to place more and more computing power onto smaller and smaller chips, but we are now pushing the physical limits of silicon. If silicon-based chips become much smaller, their performance will become unstable and unpredictable."

Xu's and his team's efforts could eventually lead to more nanoscale electronics. Plus, the project could lead to more advanced devices, since scaling down components means engineers can cram more into regular-sized gadgets.
