Claim Text:
1. A method for regulating a flow rate of a biomolecule through a fluid flow path, comprising: (a) subjecting a solution comprising said biomolecule to flow through said fluid flow path having a length using an electric field provided by a pair of electrodes at opposing ends of said fluid flow path, wherein said fluid flow path includes an internal space comprising different electrode sections that substantially oppose one another along said length, wherein each of said different electrode sections includes a non-conductive film adjacent to a conductive material, which non-conductive film is in contact with said solution; (b) changing said flow rate of said biomolecule through said fluid flow path by applying a positive or negative voltage to said different electrode sections; and (c) detecting said biomolecule or a portion thereof upon changing said flow rate of said biomolecule through said fluid flow path.
