As a method of controlling the activation of the positive-feedback loop in our predator-prey based oscillator, we successfully created this part, which can be used as a general Pops Blocker:
This part is placed downstream of a promoter and prevents any Pops from the promoter passing through this part
When an accompanying Cre Recombinase plasmid becomes activated, the enzyme produced will permanently cut a section of DNA from the plasmid containing this part
Only then, the polymerase can pass through this part and transcribe downstream genes.
We also worked on a Biosensor for measuring AHL concentrations in order to establish a Biological to Electrical Interface this summer.
Using an enzyme to hydrolize the lactone AHL would result in a local change in pH
Measuring the change in pH gives a measurement of how much AHL is present.
