Résumé

We are inspired by the morphogenesis processes that are involved in the emergence of shape and structure in living systems. We aim to engineer chemical and material organization using the two most debated mechanisms in biological development: (1) the Turing’s Reaction-Diffusion model and (2) the positional information mechanism. To explore chemical organization, we employ DNA-based reaction networks due to their accessible programmability and known chemistry.   In our experimental approach we start from temporal organization and move up to spatiotemporal patterns, such as chemical waves. Microfluidic devices are used as microreactors, in which we study the effects of curvature on the propagation dynamics of waves. Finally, we present our strategies to go from chemical spatiotemporal to chemical stationary patterns, and how we plan to link chemical to material morphogenesis.
