Physical Assembly of Life-Like Systems

Abstract

Searching for the transition between inanimate matter and living matter, it seems reasonable to consider that soft matter and elementary self-assembled and self-organized systems played a role in the emergence of life. But as stated by Oparin, 'Natural selection has completely wiped off the face of Earth all the intermediate forms of organization of primary colloidal systems and of the simplest living things'.

The ambition of our research group is to construct artificial systems, integrate them and assemble them towards living systems. Our approach is based on the identification of essential features and properties of living systems and their re-engineering in minimal systems. Among the key functions of life, we focus on metabolism with a minimal approach in which we integrate functions in compartments. Those take the form of vesicles, droplets, and membraneless organelles (1-3) and function under out-of-equilibrium conditions.
