Patent number: 11085906Abstract: A composition for dry reagent colorimetric sensing of nanoparticles in aqueous media, including sodium borohydride (NaBH4), methylene blue (MB), and 4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid (HEPES) in the form of a powdered mixture. The composition may be formed by combining MB, HEBES, and water to yield an aqueous mixture, removing water from the aqueous mixture to yield a solid mixture, and combining NaBH4 powder with the solid mixture to yield the composition. The composition may be used to detect metallic nanoparticles an aqueous solution by combining the composition with an aqueous solution to yield a test solution, and assessing a concentration of the metallic nanoparticles in the test solution based on absorbance of light by the test solution. The composition may be provided in an assay kit for sensing nanoparticles in aqueous media.Type: GrantFiled: August 17, 2018Date of Patent: August 10, 2021Assignees: Arizona Board of Regents on behalf of Arizona State University, University of WashingtonInventors: Paul K.

Publication number: 20210186139Abstract: The present technology relates generally to protective helmets with non-linearly deforming members. Helmets configured in accordance with embodiments of the present technology can comprise, for example, an inner layer, an outer layer, a space between the inner layer and the outer layer, and an interface layer disposed in the space. The interface layer comprises a plurality of filaments, each having a height, a longitudinal axis along the height, a first end proximal to the inner layer, and a second end proximal to the outer layer. The filaments are sized and shaped to span the space between the inner layer and the outer layer. The filaments are configured to deform non-linearly in response to an external incident force on the helmet.Type: ApplicationFiled: March 3, 2021Publication date: June 24, 2021Applicant: University of Washington through its Center for CommercializationInventors: Samuel R. Browd, Jonathan D. Posner, Per G. Reinhall, David L. Marver, John T. Dardis, II

Publication number: 20210037906Abstract: A protective helmet comprises an inner layer and an outer layer separated from the inner layer by a space. An interface layer is positioned in the space between the inner layer and the outer layer and includes an impact absorbing material that non-linearly deforms in response to an incident force on the protective helmet. For example, the impact absorbing material includes multiple filaments each having an end proximate to the inner layer and another end proximate to the outer layer interface, with the filaments configured to non-linearly deform in response to an incident force on the helmet.Type: ApplicationFiled: October 23, 2020Publication date: February 11, 2021Applicants: University of Washington, VPG AcquisitionCo, LLCInventors: Jonathan D.

Patent number: 10227634Abstract: The present disclosure relates generally to the integration of isotachophoresis (ITP) and isothermal nucleic acid amplification methods such as recombinase polymerase amplification (RPA). One aspect of the disclosure relates to a method for concentrating and amplifying a nucleic acid, the method including an isotachophoresis device, the isotachophoresis device including a porous matrix, and first and second electrodes, having a leading electrolyte, a trailing electrolyte and a set of isothermal nucleic acid amplification reaction reagents disposed in the porous matrix as described herein, and applying a voltage across the first electrode and the second electrode for a time sufficient to provide a first isotachophoresis (ITP) plug comprising an amplification product of the nucleic acid, wherein the concentration of the nucleic acid is substantially higher in the first FTP plug than in the first and/or second fluids outside of the first ITP plug.Type: GrantFiled: April 14, 2016Date of Patent: March 12, 2019Assignee: University of WashingtonInventors: Jonathan D.

Patent number: 7645368Abstract: According to some embodiments, a method, system, and apparatus for providing an orientation independent electroosmotic pump. In some embodiments, the method includes an anode and a cathode at different electrical potentials, the anode and cathode are each sealed in an ion-exchange membrane and at least partially immersed in an electrolyte contained in a reservoir of an electroosmotic pump, collecting gases generated by electrolytic decomposition of the electrolyte within a space defined by the ion-exchange membranes that seal the anode and cathode, recombining the collected gases to produce a liquid using a catalyst, the catalyst being located outside of the reservoir, and introducing the produced liquid into the fluid reservoir through an osmotic membrane.Type: GrantFiled: May 10, 2005Date of Patent: January 12, 2010Assignee: Intel CorporationInventors: Alan M.
