Design List

Our receptors

We designed entirely the receptors and amplificators of those designs.

	YFP concentration This design relies on a TetO-array which allow us to concentrate YFP-TetR fusion proteins.
	T7 RNA polymerase diffusion In this design, we introduce the use of the T7 polymerase both as the transfer molecule and as the auto-amplification system.
	tRNA amber diffusion The tRNA amber is the smallest molecule we are trying to get pass the nanotubes.

Using bistable switches

We noticed that using natural or artificial bistable switches in the receiving cell gave us a receptor and an auto amplifier. One molecule carefully chosen could toggle the switch in another position. All we have to do is see if it diffuses through the nanotubes.

	ComS diffusion We took advantage of a switch already existing in B.Subtilis (the ComK/ComS switch) and tried to see if we could toggle it from one state to the other using molecules diffusing through the nanotubes.
