Devices with electrokinetic elements are disclosed as well as their method o f microfabrication for use in micro-scale analysis, mixture separation and reaction. The devices consist of solid hydrophilic-matrix films (2) that hav e been microfabricated into a variety of micro-scale structures. These structures include hydrophilic-matrix conductors (2) for electrokinetic species transport and separation. They also include hydrophilic-matrix cladding containing chemical species adjacent to either an open conduit or a hydrophilic matrix conductor. Also described are other integrated microstructures consisting of hydrophilic-matrix materials (2) such as micro - reaction zones for retaining chemical species for on-chip chemical reactions and integrated detection structures for on-chip species detection. In genera l, a hydrophilic matrix on a substrate (1) functions as a conductor that is covered by an electrically insulating, preferably water permeable material ( 3).
