To enable detailed studies of interactions between nanoparticles and their environment the correlations various nanoparticle properties, one must go beyond ensemble averages toward single-particle measurements. However, current methodologies for single-nanoparticle analysis charge size either lack flexibility to study dynamic processes on level or are highly specific require complex microfluidi...

where P represents a macromolecular ion in solution and P(HA), its complex with n moles of a small uncharged constituent, HA, of the solvent medium. It was assumed that the complex migrates with a greater electrophoretic mobility than the uncomplexed macromolecule and that equilibrium is established instantaneously. Computer solution of the conservation equations showed that under appropriate c...
