Self-assembly

Self-assembly is the process by which an organized structure spontaneously forms from individual components, as a result of specific, local interactions among the components. When the constitutive components are molecules, the process is termed molecular self-assembly.

    It’s not known how life’s essential properties of replication, metabolism and compartmentalization were first integrated. Two recent articles now shed light on how metabolic characteristics may be incorporated into replicating systems, harnessing an external energy source to increase their rate of replication and acquiring catalytic activity.

    Equilibrium self-assembly processes find free-energy minima but no such general statement holds for systems driven out of equilibrium. A new study has employed laser-induced convective flows to achieve dissipative self-assembly across multiple scales with universal growth and fluctuation statistics.

    A balance between order and disorder provides living materials with just the right amount of disorder needed to sustain life. This feature is currently not found in synthetic materials. Now, a route to the production of composite membranes that are simultaneously stiff and reconfigurable upon contact has been developed.
