“Metabolic DNA Systems Inspired from Life: Protocells and Systems with Lifecycles”
Living self-organizing systems operate far-from-equilibrium and display energy-dependent adaptive functionalities. They can serve as an inspiration to promote complexity and life-like functions in soft matter systems, which include for instance to pre-organize temporal behavior or install mechanisms for complex adaptative behavior. Along these lines, I will discuss two avenues towards autonomous and adaptive DNA active matter systems with simplistic metabolic reaction networks inside. On the one hand, I will discuss the formation of DNA-based protocell architectures with the ability to house abiotic catalysts driving downstream morphological adaptations. On the other hand, I will discuss the use of ATP as a chemical fuel to drive chemically fueled out-of-equilibrium systems using activation/deactivation networks. The latter allows to program self-assemblies and materials with lifetimes and programmable steady state dynamics.
