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. Now we are enjoying the advantage of Ultra Large Scale IC (ULSI), but at least today we cannot implement a somewhat large logic ABC containing several levels of logic gates in actual experiments.
Our project is to provide a new methodology for building up fully extensible logic ABC. We are going to produce biologic logic gates such as NAND, NOR, NOT for some biological conveniences. In other words, modern logic IC are built upon these three gates-- NAND, NOR and NOT. Logic gates are only the basic components of logic IC, on the other hand, the more important factors we think which make IC to be easily enlarged are: reducing the size, power and response time of components; tuning components to eliminate interference; calibrating components for interconnection. Cis-acting elements may provide smaller scale than trans-acting ones, while the other two factors can be achieved by novelly designed wires and standardization. We will also demonstrate an ABC made by these biologic logic gates.
This ABC may not be large, but the important factors we implement in it will naturally make it fully extensible. IC has been born for 50 years and how hugely it impacts our modern life! So, what about biologic logic circuit in next 50 years? A new world is waiting...
