A research group led by Naomi Sugimoto, director of the Frontier Institute for Biomolecular Engineering Research of Konan University, is trying to find ways to replace semiconductors with biotic DNA sequences in processing information.
Today’s computers use semiconductor-based LSIs, but as the computing power is determined by the level of LSI integration, semiconductor processing technology is approaching its limit.
The research group uses DNA sequences known as “telomere” to create a functional nano-scale molecular switch that accepts stimuli by external metal ions.
The switch is designed in such a way that information input into the telomere results in an output of four patterns.
“There is a possibility that a single telomere could be worth hundreds of millions of transistors,” according to Director Sugimoto.
