Scientists Make DNA Wires That Carry Electric Current
DNA, the molecule at the heart of life, is the most powerful and sophisticated information storage device in existence. So it’s no wonder that scientists are attempting to harness its capabilities in computing and electronics. Not only does DNA have the capacity to store vast amounts of data, but it also provides the opportunity to surpass current limitations on reducing the size of electronics. Although we’ve drastically shrunk computers since their advent, scientists can only go so far because a minimum space between transistors-- the main building block of electronic devices-- is required to prevent interference. This means that processors can’t be designed much smaller than what we have around today. DNA could provide us with a unique way get around this, but unfortunately, scientists have faced a considerable challenge with using it in the field of “molecular electronics,” or the use of molecules in the production of electronic components.
