Information ratchets rely on the presence of kinetic asymmetry in a chemical reaction network and have been mostly applied for the design of molecular machines, and more recently, materials, and molecules. Here we extend the use of information ratchets to the field of molecular recognition. 5/n

The approach mimics ‘kinetic proofreading’ by error-correcting enzymes that are used by nature for processes in which selectivity based on thermodynamics is insufficient, for example, DNA replication. 4/n

Under non-equilibrium conditions, the distribution between ‘red’ and ‘green’ duplexes is no longer determined by the thermodynamic equilibrium constant, but by the rates at which duplexes are depleted and regenerated in a chemical reaction network. 3/n

In the paper we show that an information ratchet mechanism can be used to improve the selectivity in molecular recognition between DNA strands. By operating under an energy-dissipating kinetic-control regime the selectivity in DNA duplex formation increases from 2:1 at equilibrium to 6:1. 2/n

Great to see this paper published today !! Phenomenal work by @benjaminoacid.bsky.social in collaboration with Erica Del Grosso and Francesco Ricci at Rome ‘Tor Vergata’. Many thanks to @epenocchio.bsky.social for contributing. 1/n

Transducing chemical energy through catalysis by an artificial molecular motor - Nature

A cross-linked polymer gel driven by artificial molecular motors transforms chemical energy into mechanical force, achieving powered contraction and re-expansion, demonstrating a considerable advance in understanding energy transduction mechanisms and informing nanotechnology design principles.
