Okay, so I've taken a look at the stuff that Weiss linked us.
His PPG is essentially identical to the construct we proposed--see figure 3 on the conference paper. One thing to note is that the data in the paper are almost all in simulation. There are few experimental results (as far as I can tell, the only experimental results don't use the PPG at all--instead, they use the sender/receiver setup, kind of like we were planning to do in our initial experiments). Figure 7 is where all the experiments are summarized--he has a nice ring wave like propagation graph in 7b. He mentioned that he's working on getting experimental results--it's quite possible that he's running into some pulse vs. line, diffusion, noise, etc. issues. It's definitely worth following up with him to see exactly where he is. If he's almost got the PPG working, then maybe we should focus on ways of applying the PPG (the maze idea is cool, but I'm sure there are others). If his PPG isn't quite working then we can continue largely as planned. Kxjin 01:44, 14 Jun 2005 (EDT)
- "The maze solving" project was presented at last year's iGEM (aka SBC). If you search on this wiki you'll find the abstract of the "Dynamics control in a coordinated multi-cellular maze solving system" on the mostly empty SBC 2004 page. --ASW 09:20, 14 Jun 2005 (EDT)
Also, what does having PPG plasmids that "work in liquid" mean exactly? Kxjin 01:44, 14 Jun 2005 (EDT)
