Result

After we finished our project, we started to test it. We test two part of our project. The first one is our Device One. We tested its response to Pi starvation. Here is the results diagram.

In this diagram we can find that Device one can be induced by phosphate starvation. When the concentration of dipotassium phosphate is 0.03μM we can see that our sensor reached a peak because our promoter can be activated by Pi starvation.

Next is our whole Device. We tested when the green fluorescence would vanish and red fluorescence occur. Here is another diagram.

This diagram shows that after several hours the amount of green fluorescence decreases, which means the work has been done and red fluorescence will occur.

This result clearly pointed out that our product can work smoothly. The Pi starvation promoter is working well too. Our experiments have reached a success at last.
