Polymer brushes comprising two different chemistries can induce motion of adsorbed nanometer-scale objects. Topographical variations of the brushes occurring along with nanometer phase separation after exposure to selective solvents result in variations of surface forces between the substrate and the adsorbed object, inducing its motion (see figure).
