  • Patent number: 9028775
    Abstract: This technology is a method and apparatus for the semi-continuous measurement of the concentration of constituents of airborne particles which couples a laminar flow, water condensation particle collector to a microfluidic device for assay of particle chemical composition by electrophoresis. The technology has been used for the assay of sulfates, nitrates, chlorides, and organic acids contained in fine and submicrometer atmospheric particles. For these compounds the apparatus and method described is capable of one-minute time resolution at concentrations at the level of micrograms of analyte species per cubic meter of air. Extension to other analytes is possible.

  • Publication number: 20110257642
    Abstract: This invention provides a relatively fast and safe method of producing a permanent or nearly permanent skin image, design, or tattoo similar in appearance to that of a solar tattoo. A protective design template is placed on the skin and a cryogenic agent applied to freeze exposed portions of the skin, producing hypopigmentation. An image is defined by the contrast between the treated (hypopigmented) skin and the adjacent untreated skin.

  • Patent number: 7169272
    Abstract: Construction and characterization of microfabricated recessed disk microelectrodes (RDMs) of 14 and 55 ?m diameter are reported. The work reported here makes several new contributions to the current literature on microfabricated RDMs. Hybrid blamers were constructed by fusion of vesicles of dimyristoylphosphatidyl choline (DMPC), which forms the top layer, with ethanol-rinsed SAMs of hexadecanethiol on gold, which form the bottom layer. Gramicidin A was included in the modifying solutions to incorporate it into hybrid blamers.

  • Patent number: 7144486
    Abstract: Microcavities and micropores that are microscopic (<1 mm) in width and depth and contain any number of individually-addressable electrodes, separated by insulators, along the walls of each cavity. The conducting materials, and the insulator materials can be deposited alternately onto a starting substrate, which is typically an oxidized silicon wafer or polyimide film, but may be any substrate that shows good adhesion to the materials layered on it. The cavities are etched through these layers, perpendicular to the plane of the substrate, exposing the layers at their edges. Pores may be carved entirely through the device.
