Writing down reaction-diffusion equations with DNA |
|
Résumé |
The question that motivates my research is: to what extent non-equilibrium molecular systems can create
order at the macroscopic scale, in particular spatial order.
A major mechanism of spatial self-organization is reaction-diffusion. For decades reaction-diffusion has
been experimentally investigated using the Belousov-Zhabotinsky reaction and its cousins. The problem is
that the dynamics of this reaction is difficult to change, limiting the number of questions that one can
address using this system.
As a possible solution to this drawback I will introduce an approach to engineer chemical dynamical
systems using DNA and three enzymes. I will then describe the experimental implementation of various
reaction-diffusion patterns with this system: monostable and bistable traveling fronts, predator-prey
waves and spirals, and immobile fronts. Finally, I will suggest open theoretical questions that we have
encountered while |
