The present invention provides an apparatus and methods for the electrical detection of molecular interactions between a probe molecule and a protein or peptide target molecule, but without requiring the use of electrochemical or other reporters to obtain measurable signals. The methods can be used for electrical detection of molecular interactions between probe molecules bound to defined regions of an array and protein or peptide target molecules which are permitted to interact with the probe molecules.

Protein and peptide sensors using electrical detection methods

The present invention provides an apparatus and methods for efficient, high-throughput electrical or electrochemical detection of biomolecules. More specifically, the invention provides an apparatus in which an independent set of electrodes is used to increase the occurrence of a desired bio-conjugation event at a test site.

Method for enhanced bio-conjugation events

The present invention provides a method to characterize, optimize, and control the quality and production of hydrogel media. Additionally, the present invention provides a method for determining the size, size distribution, and spatial distribution of the pores of a porous substrate. More particularly, the invention provides a method for determining the size, size distribution, and spatial distribution of the pores of a polymeric hydrogel-based substrate.

Method for characterization and quality control of porous media

An electrolyte for an electrochemical cell is described comprising two or more polyanion-based compounds of the general formula:

Multi-polyacid electrolytes for electrochemical cells and cells using

A material for use as an electrode, and particularly the anode (20) of an electrochemical device, such as an electrochemical capacitor device (10). The material is a multicomponent alloy material, including a host matrix material consisting of antimony, and at least one modifier element selected from the group consisting of bismuth, nickel, cadmium, zinc, silver, manganese, lead, lithium, and combinations thereof.

Electrode materials and electrochemical devices using same

A hybrid capacitor with improved energy density employs a cathode including an organic material and optionally a gel, solid, or composite electrolyte material. However, like conventional electrolytic capacitors, said hybrid capacitor employs a valve metal and its respective oxide dielectric layer on the anode side of the cell.

Capacitor

A capacitor (100) includes first and second electrodes (102, 103) that each have an electroactive material (115, 120) disposed on a metallic substrate (105, 110). A solid electrolyte (125) including a polyacid is positioned between the first and second electrodes (102, 103). Polyacids are relatively low in cost, and their high ionic conductivity together with their thermal stability makes polyacids a viable alternative to solid polymer electrolytes.

Electrochemical capacitor with solid electrolyte

A method for making high power electrochemical charge storage devices, provides for depositing an electrically conducting polymer (16), (18), onto a non-noble metal substrate (10), which has been prepared by treatment with a surfactant. Using this method, high power, high energy electrochemical charge storage devices may be fabricated with highly reproducible low cost.

Method for fabricating a conductive polymer energy storage device

An electrochemical cell, particularly an electrochemical capacitor device (30) includes first and second electrodes (24) and (28) having an electrolyte (26) disposed therebetween. At least one of the electrodes (24) is fabricated on a substrate (12) and includes a multilayer composite electrode active material disposed thereon. The multilayer composite electrode includes first and second layer (16) and (22), in which the ratios of electroactive materials therein is varied so as to promote good adherence to the electrode substrate as well as excellent electrochemical performance.

Composite multilayer electrodes for electrochemical cells

A capacitor (100) includes first and second electrodes (102, 103) an adhesive electrolyte (125) positioned therebetween. The adhesive electrolyte (125) includes an organic polymer and an inorganic component, which is either a polyacid or a polysalt.

Electrochemical capacitor with hybrid polymer polyacid electrolyte

An electrochemical battery cell (10) including a zinc electrode (20), and may be fabricated with an electrolyte (50) system including an electrolyte active species and a modifier. The electrolyte active species is typically a metal hydroxide such as KOH or NaOH, while the modifier may be a porphine such as a metal porphine, and/or a polymeric material. The polymeric material may be, for example, a polyvinyl resin such as polyvinyl alcohol or polyvinyl acetate. The resulting electrolyte typically includes between 3 and 10 weight percent of the polyvinyl resin, 5 and 50 weight percent of the metal hydroxide, and between 1 PPM and 1 wt % of the modifier. Employing such an electrolyte in a cell including a zinc electrode results in an energy storage device having improved power density and substantially longer cycle life.

Rechargeable electrochemical cell with modified electrolyte

An electrochemical cell is provided with first (10) and second (11) electrodes and a solid polymer electrolyte (15) disposed therebetween. The electrodes include a current collecting layer, a layer of electrode active material, and a layer of an electrically conductive, polymeric protection material disposed therebetween. The protective layer protects, for example, the current collecting layer from the deleterious effects of the acid or alkaline electrolyte active species found in most electrochemical cells. The protective layer is formed of an intermetallic compound dispersed through a layer of appropriately chosen polymeric material.

Electrically conductive polymeric coating for an electrochemical charge

An electrochemical cell is provided with first (10) and second (11) electrodes and a solid polymer electrolyte (15) disposed therebetween. The solid polymer electrolyte is preferably fabricated by providing a linear powdered polymeric precursor material which is thereafter heated to temperatures sufficient to drive off moisture and in the presence of an electrolyte active species. The electrolyte active species is preferably an acidic electrolyte active species which has the effect of protonating the powdered polymeric precursor material. Electrochemical cells fabricated using these devices demonstrate performance characteristics far better than those available in the prior art.

Electrochemical cell having a polymer electrolyte

An electrochemical capacitor cell (140) is provided with first and second electrodes (146) (148), and a solid polymer electrolyte (154) is disposed therebetween. The electrodes may either be of the same or different materials and may be fabricated from ruthenium, iridium, cobalt, tungsten, vanadium, iron, molybdenum, hafnium, nickel, silver, zinc, and combinations thereof. The solid polymer electrolyte is in intimate contact with both electrodes, and is made from a polymeric support structure having dispersed therein an electrolyte active species. Also a method of fabricating a biopolar electrochemical charge storage device by assembling at least the first and second bipolar subassemblies together with the second layer of electrode active material for the first bipolar subassembly in direct contact with the first layer of electrode active material for the second bipolar subassembly without a current collector disposed therebetween.

Bipolar electrochemical charge storage devices and a method of

A method for making high power electrochemical capacitors provides for depositing an electrically conducting polymer (20) (22) onto a non-noble metal substrate (10) which has been prepared by coating with an adhesion enhancing material (16) (18). Using the method, high power, high energy devices may be fabricated by arranging a plurality of individual capacitor cells into a stacked, bipolar device.
