Accelerated Self‐Replication under Non‐Equilibrium,Periodic Energy Delivery

Self‐replication is a remarkable phenomenon in nature that has fascinated scientists for decades. In a self‐replicating system, the original units are attracted to a template, which induce their binding. In equilibrium, the energy required to disassemble the newly assembled copy from the mother template is supplied by thermal energy. The possibility of optimizing self‐replication was explored by controlling the frequency at which energy is supplied to the system. A model system inspired by a class of light‐switchable colloids was considered where light is used to control the interactions. Conditions under which self‐replication can be significantly more effective under non‐equilibrium, cyclic energy delivery than under equilibrium constant energy conditions were identified. Optimal self‐replication does not require constant energy expenditure. Instead, the proper timing at which energy is delivered to the system is an essential controllable parameter to induce high replication rates.
