Hi everybody! We are the Bologna University Team; this is our first time in iGEM and we are very excited about it!

Project

Our project consists in a Genetic Schmitt Trigger. "When the input is higher than a certain chosen threshold, the output is high; when the input is below another (lower) chosen threshold, the output is low; when the input is between the two, the output retains its value. The trigger is so named because the output retains its value until the input changes sufficiently to trigger a change. This dual threshold action is called hysteresis."

It is worth to remark that the invention of the Thermionic Trigger was a direct result of Otto Schmitt's study of nerve propagation in squid nerves: it is the perfect example of inventing an artificial method to imitate a natural process. We think it's time for Schmitt trigger to come back home in Bio.

-The Team's project consists of a Genetic [http://en.wikipedia.org/wiki/Schmitt_trigger Schmitt Trigger], a comparator circuit with an incorporated positive feedback. The main feature of this kind of circuit is the so called hysteresis, which is obtained through a dual threshold action: being T<sub>H</sub> and T<sub>L</sub> the two thresholds, if input is higher than T<sub>H</sub>, output is at an high level; in case of input being lower than T<sub>L</sub>, output results low. Instead, when input is between T<sub>H</sub> and T<sub>L</sub>, output retains its value.
