Latest Patents

One of his latest patents is titled "Approach to contacting nanowire arrays using nanoparticles." This patent presents an in situ method for connecting and electrically contacting vertically aligned nanowire arrays using conductive nanoparticles. The utility of this approach is demonstrated through the development of a gas sensing device that employs the nanowire assembly. In this process, well-aligned, single-crystalline zinc oxide nanowires were grown via a direct thermal evaporation method at 550°C on gold catalyst layers. Electrical contact to the top of the nanowire array was achieved by creating a contiguous nanoparticle film through the electrostatic attachment of conductive gold nanoparticles exclusively onto the tips of the nanowires. The resulting gas sensing device was found to be sensitive to both reducing (methanol) and oxidizing (nitrous oxides) gases. This assembly approach is versatile and can be applied to any nanowire array requiring a top contact electrode.

Another significant patent is a "Method for operating a sensor to differentiate between analytes in a sample." This method involves determining an input profile for the sensor that enhances the difference in output profiles between two analytes. The process includes evaluating the sample output profile against the output profiles of the first and second analytes to identify which analyte is present in the sample.
