Resumen de Building a genetic machine.
The article presents two diagrams showing how a genetic TNT detector could be constructed and how a TNT detector works. A living TNT detector that reveals buried land mines could be made with genetic "Goldilocks" circuits that fluoresce. One design for a Goldilocks genetic circuit uses four interacting parts: a sensor, upper and lower thresholds, and an inverter. Each part has a distinctive behavior: the amount of protein output it produces varies as a function of the amount of input protein it receives.
