The present invention is directed to a device that comprises a biomolecular processor and one or more nanotubes. Each biomolecular processor comprises a bioreactor chamber defined by a solid substrate, a plurality of spaced support structures within said bioreactor chamber and attached to the solid substrate, and one or more capture molecules immobilized to some or all of said plurality of spaced support structures, said one or more capture molecules suitable to bind to a portion of a target nucleic acid molecule in a sample. The device also comprises one or more nanotubes defined by the solid substrate and fluidically coupled to the bioreactor chamber.
