ABSTRACT:
Small particles, of macromolecular size or the like, are separated in a liquid by size by applying electric fields of predetermined distributions in time and space to enhance the Brownian motion of the particles so as to favor motion of particles of a particular size. When the particles are separated by size they can be removed from the region in which they have accumulated and they can be collected by size.
