Decoding the Wonders of Nanomachines

Transducing chemical activity into motion serves as a pivotal element in the nanomachine mechanism. The enhanced molecular mobility has sparked controversy within the scientific community. Some studies indicate a substantial increase in mobility post-reaction, while others report no observable changes. In this investigation, we delve into the diffusion amplification following an exothermal reaction between two interacting species in an explicit solvent, employing extensive Langevin dynamics simulations. Our examination explores the impact of various parameters, including reactants' geometry and reaction energy. Our findings reveal no significant boost in the products of the exothermal reaction. However, when a polar solvent is introduced, a subtle increase in diffusion becomes apparent.
