Patent number: 7175885Abstract: The present invention provides a combinatorial approach for preparing arrays of chemically sensitive polymer-based sensors which are capable of detecting the presence of a chemical analyte in a fluid in contact therewith. The described methods and devices comprise combining varying ratios of at least first and second organic materials which, when combined, form a polymer or polymer blend that is capable of absorbing a chemical analyte, thereby providing a detectable response. The detectable response of the sensors prepared by this method is not linearly related to the mole fraction of at least one of the polymer-based components of the sensors, thereby making arrays of these sensors useful for a variety of sensing tasks.Type: GrantFiled: January 24, 2001Date of Patent: February 13, 2007Assignee: California Institute of TechnologyInventors: Nathan S. Lewis, Robert H. Grubbs, Robert D. Sanner, Eric J. Severin

Patent number: 7163715Abstract: Thermal spray processing and cold spray processing are utilized to manufacture porous starting materials (such as tube stock, wire and substrate sheets) from biocompatible metals, metal alloys, ceramics and polymers that may be further processed into porous medical devices, such as stents. The spray processes are also used to form porous coatings on consolidated biocompatible medical devices. The porous substrates and coatings may be used as a reservoir to hold a drug or therapeutic agent for elution in the body. The spray-formed porous substrates and coatings may be functionally graded to allow direct control of drug elution without an additional polymer topcoat. The spray processes are also used to apply the drug or agent to the porous substrate or coating when drug or agent is robust enough to withstand the temperatures and velocities of the spray process with minimal degradation.Type: GrantFiled: December 30, 2002Date of Patent: January 16, 2007Assignee: Advanced Cardiovascular Systems, Inc.Inventor: Pamela A. Kramer

Patent number: 7135295Abstract: A protein comprising an antigen-binding portion formed by two cooperating peptide sequences of FIGS. 3A and 3B of the application. The protein may alternatively comprise an altered antigen-binding portion where at least one of the peptide sequences is an altered sequence, an altered sequence being a sequence of FIG. 3A or 3B in which one or more of an amino acid residue has been added, deleted or replaced by another amino acid residue. The altered antigen-binding portion retains substantially the same antigen-binding specificity as said antigen-binding portion. Also disclosed are apparatus, systems and methods for detecting small assayed molecules in a sample using the protein.Type: GrantFiled: January 25, 2000Date of Patent: November 14, 2006Assignees: Yissum Research Development Company of the Hebrew University of Jerusalem, Yeda Research and Development Co. Ltd., Biosensor Applications Sweden ABInventors: Itamar Willner, Zelig Eshhar

Patent number: 7135075Abstract: An aqueous solution for depositing an inorganic corrosion resistant coating on a metal substrate is disclosed. The aqueous solution comprises a film-forming agent, a supplemental anion, and a substrate activator. The film-forming agent is a vanadate salt that forms the corrosion resistant coating. The supplemental anion accelerates the rate at which the corrosion resistant coating is formed. The substrate activator serves to remove any existing oxides from the metal substrate prior to the formation of the corrosion resistant coating. The present invention additionally covers objects so coated and methods of application.Type: GrantFiled: January 20, 2004Date of Patent: November 14, 2006Assignee: The Ohio State UniversityInventors: Rudolph G. Buchheit, Hong Guan, Valerie N. Laget

Patent number: 7125580Abstract: A sample collection substrate of aerogel and/or xerogel materials bound to a support structure is used as a solid phase microextraction (SPME) device. The xerogels and aerogels may be organic or inorganic and doped with metals or other compounds to target specific chemical analytes. The support structure is typically formed of a glass fiber or a metal wire (stainless steel or kovar). The devices are made by applying gel solution to the support structures and drying the solution to form aerogel or xerogel. Aerogel particles may be attached to the wet layer before drying to increase sample collection surface area. These devices are robust, stable in fields of high radiation, and highly effective at collecting gas and liquid samples while maintaining superior mechanical and thermal stability during routine use. Aerogel SPME devices are advantageous for use in GC/MS analyses due to their lack of interfering background and tolerance of GC thermal cycling.Type: GrantFiled: June 6, 2005Date of Patent: October 24, 2006Assignee: The Regents of the University of CaliforniaInventors: Fred S. Miller, Brian D. Andresen
