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.

Based on the “Latch and Enable Control”conception of "Flip-flop" and synthetic biology, we designed the Genetical 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 and then disappears. Thus, the immediate response to emergency (input change) enables our design to detect signal variation in a short time, which is beneficial for the control of biology systems.
