We would hopefully have the lacZ system already from the simpler arsenic setup. So that's Device 3 sorted, but we need to engineer functioning Devices 1 and 2.

I'm just gonna stick up random project notes here, since they're easier to access and move around if they happen to be online already.

I think the most promising version of the arsenic biosensor is the second one, combining an acid and an alkali output. Now, the preliminary tests for this that need to be done are as follows:

  • Experiments with different copy numbers of the arsenic sensor, to see if it's possible to develop sensors of different sensitivities
