We report a reaction driven system where aminolysis of ester at poly(amidoamine) (PAMAM) dendrimer interface converts chemical energy dissipation into directed fluid flow and colloidal motion. Generation dependent dendrimer interfaces produce localized gradients driving flow, while bulky esters impose steric gating. Dendrimer-coated colloids exhibit substrate and generation dependent enhanced diffusion.
