Both a repressor (coupled to an inverter) or an activator can be used as sensor parts of the system. In our case we used AlcR (from ''aspergillus nidulans''), respectively XylR (from ''pseudomonas putida'') regulatory proteins in order to sense compounds present in smoke and thereby to induce the different parts of our network.

Upon sensing the specific molecule the circuit gets activated and our SmoColi bacteria start notifying us about the presence of toxic substances in air. For a detailed description of the circuit design please [https://2011.igem.org/Team:ETH_Zurich/Biology/Detector click here].
