IGEM:IMPERIAL/2009/EncapsulationP3 Trigger

The trigger for the cell death is heavily dependant on the project application and the cell encapsulation mechanism. Possible ideas proposed include:
 * Hypoxic conditions caused by complete encapsulation in a compound through which oxygen cannot diffuse (not for the alginate capsule, only the CaCO3/ salt capsule)
 * Timer mechanism continuing from drug production timer/threshold
 * External factor added manually to trigger genetic removal response.
 * Environmental Sensor mechanism, different environment once capsule has been formed. depends on capsule again
 * RNA thermometer (biobrick characterised by TU Delft '08)
