Our Project:
Extensible Logic Circuit in Bacteria
Logic Artificial Biologic Circuit (ABC) and logic Integrated Circuit (IC) are both composed by logic gates and wires. Though we have been enjoying the advantages of Ultra Large Scale IC (ULSI), we still cannot implement in real experiments a somewhat large-scaled logic ABC with several levels of logic gates in it.
Our project is to provide a new method for building up a fully extensible logic ABC. For some biological convenience, we are going to produce such biologic logic gates as NAND, NOR, NOT which are exactly the basis for modern logic IC. Anyway, logic gates are just the basic components of logic IC. There are factors considered more important to let IC to be easily enlarged. For example, size reduction, the power and response time of the components, modulation of the components to eliminate interference, calibration of them for their interaction. Cis-acting elements may present a smaller scale than trans-acting ones, while the other two factors can be achieved by novelly-designed and standardized wires. We are also going to demonstrate an ABC made by these biologic logic gates.
Such an ABC may not be large, but the important factors we implement in it will naturally make it fully extensible. IC has existed for 50 years, and now how huge its impact is on our modern lives! Then what about the biologic logic circuits in the next 50 years? A new world is waiting...
