Hi Luis Carlos,
First of all, thank you for your 'two cents', it is an interesting
information for us.
About the attractant concentration you mentioned,
please, could you tell us the size molecules you used?
Regards
Hi Nora,
Max will probably have more insightful comments, but here are my two cents:
- I think you can make a bit bigger the transmitter/receptor. E. Coli
(a human gut bacteria used very often in research) radius is 0.5microm
to 1microm (500 to 1000 nm) and 2 microm long. I don't think we want
to go smaller than that.
- About concentration, regarding my experience with bacteria (so I am
talking for particles used for routing purposes, not for information
encoding), they are sensitive to attractant concentration, broadly
speaking, from 1mM (mili Molar, this is 0.001 moles* per litre) to
tens of nM (nanomolar, 10^-9 moles per litre).
A mole (un mol) it's Avogadros number of particles (about 6.022*10^23)
Looking forward to work side by side to all of you in Barcelona!

Hi all again,
There is attached an excel file where you can find a list of parameters we
use in the simulations, such as dimension space, particle radius,
Coefficient diffusion and so on.
Some of them we are not sure if they are realistic or not.
If somebody has sources where we can find the values for that figures or any
comment could you add it the document and sent it back?
Thanks
Nora
