Claim Text:
1. A device for isolating nucleic acids, comprising: a quartz-based solid phase extraction matrix; and an electroosmotic pump (EOP) operationally coupled to the quartz-based solid phase extraction matrix to elute the nucleic acids, wherein the EOP comprises a plurality of electroosmotic membranes comprising one or more positive electroosmotic membranes and one or more negative electroosmotic membranes disposed alternatively and a plurality of electrodes comprising one or more cathodes and one or more anodes, wherein at least one cathode is disposed on one side of one of the electroosmotic membranes and at least one anode is disposed on another side of that electroosmotic membrane and at least one cathode or anode is disposed between a positive electroosmotic membrane and a negative electroosmotic membrane, and wherein the EOP generates a pressure of greater than or equal to 1 PSI by application of a voltage of less than or equal to 3 volts.
