The molecular signal AHL is considered as the current of electric circuit, the generator, amplifiers, blocks and detector cells are constructed with the parts provided by MIT and then are equipped in series in order to achieve the cellular and molecular biological diode.

Flip-Flop, a huge family of basic electric elements, is widely applied to the field of electric circuit and construction of database. One of the most common member of this family is RS Flip-Flop, the key part of which is a clock-controlled element. Based on the conception of "Flip-flop" and synthetic biology, we designed the Genetically RS FLIP-FLOP whose output signal(Green Fluorescence) is regulated by additional input signal( the addition of IPTG). The GFP expresses only when the input signal changes. Thus, the immediate response to emergency (input change) enables our design to detect signal variation in a short time, which is beneficial for process control because of its time-saving character.
