Abstract:
A method for enhanced transportation of materials, comprising:providing a device, comprising a plurality of fluidic channels; adding a fluid containing an effective concentration of 3-(N-ethyl-N,N-dimethylammonium)propanesulfonate NDSB into at least one of said fluidic channels; controllably transporting at least a first discrete fluid volume to a first location within said device, said first discrete fluid volume comprising at least two differently charged species wherein the 3-(N-ethyl-N,N-dimethylammonium)propanesulfonate NDSB reduces the electrophoretic mobility of the at least two differently charged species in the at least first discrete fluid volume relative to an electroosmotic flow of said at least first discrete fluid volume such that the first discrete fluid volume remains substantially unsmeared during transport to said first location.
