Method and apparatus for generating electric fields and flow distributions for rapidly separating molecules

An apparatus for generating electric fields in a fluid for separating molecules comprising:

• a region for receiving the molecules to be separated;
• a first set of fluidic channels connected to opposing sides of the region for injecting a first electrical current into the region;
• and
• a second set of fluidic channels connected to opposing sides of the region for injecting a second electrical current into the region simultaneously with the first electrical current,
• wherein the apparatus is configured to apply the first and second electrical currents simultaneously to create a uniform electric field across the region orientable at a plurality of angles for separating the molecules.
