Self-assembly is both an advantageously spontaneous process to organise molecular or colloidal entities into functional superstructures and a key-feature of how life builds its components. However, compared to their living counterparts, synthetic materials made by self-assembly usually lack some of the interesting properties of living systems such as multicomponent character or capability to adapt, transform and evolve. In this presentation, I will describe two different systems where life-like properties can emerge from self-assembled synthetic materials.I will first show that user-defined and elaborate nanostructures can be obtained by the isothermal self-assembly of hundreds of different DNA bricks and proteins with a unique capability to optimise, adapt, evolve and even completely transform, either spontaneously or under command. At a micro- to macro-scopic scale, I will describe self-assembled colloidal crystals evidencing other interesting life-like properties, such as dissipative character or living crystallisation.
