Abstract:
A method for moving charged molecules under electrophoretic conditions through a medium in a movement area by the application of a plurality of electric fields employing a device comprised of:a device for moving charged particles through a medium employing an electric field, said device comprising:an electrically non-conductive solid support polymeric card having an upper surface;a main trench in said solid support having capillary dimensions and extending downward from said upper surface;a plurality of branch trenches having capillary dimensions on said main trench;a medium in said trenches; anda plurality of electrodes positioned to be in contact with said medium and to control electrophoretic movement in said branch trenches in accordance with the size, shape and charge of said charged particles;said method comprising:moving electrophoretically in at least one of said branch trenches or said main trench by means of said electric fields in said medium first charged molecules into contact with second charged molecules;whereby said charged molecules are brought into contact and react.
