Abstract: This Invention, a kind of DNA-based integrated circuit, with the DNA dyeing technology, the inlaying principle between anti-cancer medicine and DNA molecules, can change energy gap of DNA molecules to alter the conductivity of DNA molecules. Because that the diameter of DNA molecules is only about 2 nm, this kind of electronic element, which is not made with photolithography technologies, not only avoids the bottleneck of line width in production of photolithography-based ICs, but also limits the line width to 2 nm, much less than the minimum line width (0.13 &mgr;m or 130 nm) in semi-conductor production industry. It brings a practical approach to IC design beyond photolithography technologies, and ensures the development of ICs to micro-miniature predicted by the Moore Law.
