Abstract: A microfluidically-controlled transmission mode nanoscal surface plasmonics sensor device comprises one or more arrays of aligned nanochannels in fluid communication with inflowing and outflowing fluid handling manifolds that control the flow of fluid through the array(s). Fluid comprising a sample for analysis is moved from an inlet manifold, through the nanochannel array, and out through an exit manifold. The fluid may also contain a reagent used to modify the interior surfaces of the nanochannels, and/or a reagent required for the detection of an analyte.

Abstract: A filtration apparatus is disclosed for the removal of metals from jet fuel at high flow rates and limited pressure drops. The filter comprises a monolayer of immobilized chelating agent on packed silica gel. The filtration apparatus is particularly useful for the removal of copper from jet fuel.

Abstract: The present invention is a flexible hybrid biofuel cell power strip for use in low power applications (less than one Watt) such as trickle charging to extend the charge of conventional batteries or to power devices such as microsensors, micropumps and miniaturized medial devices. The power strip anode comprises carbon nanotubes (CNTs) that transfer electrons directly from the active center of an oxidation-reduction (redox) enzyme to a flexible, conductive anode substrate. This allows the building of surface architectures with pore structures customized for specific applications and enzyme substrate-containing media. The cathode comprises a catalytic layer of transition metal nanoparticle catalyst in contact with air or other source of oxygen. The flexibility of the power strip allows it to be shaped into a wide variety of conformations and applications, including attachment to or implantation within living organisms.

Abstract: A method of polishing selected ceramics and metals is provided wherein the selected ceramic or metal material is rubbed against a solid surface in the presence of a nonabrasive liquid medium which only attacks the selected ceramic or metal material under friction. Examples of materials for the tribochemical polishing process includes ceramics such as silicon, silicon nitride, silicon carbide, silicon oxide, titanium carbide and aluminum nitride and metals such as tungsten. Both ceramic and metal surfaces can be polished, as in a damascene structure of an integrated circuit.
