Researchers at the University of Georgia and Gurion University of the Negev in Israel by DNA molecular manufacturing a new type of diode. This is considered to be the world’s smallest size diode. The researchers said it would promote the development of DNA components, and promote the development of molecular electronics. The function of the diode is to realize the unidirectional flow of current. More than 40 years ago, scientists have suggested that the diode and other electronic components can be miniaturized, reduced to a single molecular size. This has led to the birth of molecular electronics, and the research results of molecular electronics is expected to promote the computer technology to break through the limitations of traditional silicon devices.

In this study, the scientists used DNA to create a diode. The breakthrough of gene science makes it possible to design DNA accurately, and makes DNA become the best raw material in the study of molecular electronics.

The double helix structure of DNA consists of molecules called the base pair. The length of this new type of diode is only 11 base pairs. Typically, the length of each DNA base pair is about 0.34 nm.

DNA itself does not play the function of the diode. However, when the researchers to a position of the internal DNA insert two small Coralyne molecules, and to the applied 1.1 volts, can be found in the current through the diode of the DNA in a certain direction to 15 times stronger than in the other direction.

The scientists said that this DNA diode can be further optimized, so as to develop a molecular device can provide the actual function. The research is published in the journal Nature chemistry.
