Catalytic Molecular Walkers: Aspects of Product Release

Abstract

We study a model of multi-legged catalytic molecular walkers that abstract a class of recently developed synthetic molecular motors. We focus on their kinetics of release of catalytic product, delineating the influence of chemical kinetic parameters, geometric configuration, and loss from surface, and also contrast with bulk kinetics of product release. We show that molecular walkers can achieve a uniform rate of release over long time scales, which can be exploited in applications.
