For the next generation of logic circuits, Silicon will be replaced by DNA which is found more abundantly than the previous. The engineer at the Duke University says that replacing Silicon with DNA will significantly decrease the production costs of the circuits and also increase by many folds the scope of their manufacturing.
He demonstrated that by exposing and mixing chosen parts of the DNA with some other molecules, he could create innumerable such tiny waffle chip like structures. Another amazing property that these waffle chips have is that the nano particles can arrange themselves in order when light is made incident upon them. These chips can be tapped readily as they exhibit qualities like programmability and some other unique characteristics which make them really convenient to manufacture. As light sensitive molecules are already present in these chips, they can be further excited upon exposure to light and thereby creating new circuits.
