The controlled diffusion of polyelectrolytes across a surface is of interest for preparing ordered surface structures, studying molecule‐surface interactions (molecular friction), obtaining information about surfaces using standard molecular probes, separating large DNA fragments, and also for basic studies of the different modes of motion of polyelectrolytes along the surface. We suggest a simple scheme for studying forced surface diffusion of charged macromolecules across a surface under a conducting fluid. Some of the possible modes of motion are discussed.
