Patent number: 10151743Abstract: A method for measuring ammonia in a blood sample may involve positioning the blood sample in proximity with an ammonia gas sensor, generating a current with the ammonia gas sensor in response to ammonia gas released from the blood sample, and measuring the current generated by the ammonia gas sensor, using a current measurement member coupled with the ammonia gas sensor. A device for measuring an ammonia level in a blood sample may include a blood sample containment member, an ammonia gas sensor coupled with the blood sample containment member, and a current measurement member coupled with the ammonia gas sensor. The method and device may be used to measure an ammonia level in a blood sample as small as one drop of blood, or approximately 0.05 mL of blood.Type: GrantFiled: December 5, 2016Date of Patent: December 11, 2018Assignee: THE BOARD OF TRUSTEES OF THE LELAND STANFORD JUNIOR UNIVERSITYInventors: Thomas Richard Veltman, Chun J. Tsai, Matthew William Kanan, Gilbert Chu

Patent number: 8691729Abstract: A novel reaction discovery system that does not depend on DNA duplex formation is provided. The advantages of this system include exploring reactions conditions not possible where DNA hybridization is required. For example, the inventive reaction discovery system allows for reaction conditions using organic solvents, higher temperatures, and water-insoluble reagents, catalysts, and ligands. The invention also provides single-stranded oligonucleotide templates with substrate pairs covalently attached and methods of screening for reaction conditions that result in a direct covalent bond between the substrates. Kits are also provided for practicing this novel reaction discovery system.Type: GrantFiled: January 9, 2008Date of Patent: April 8, 2014Assignee: President and Fellows of Harvard CollegeInventors: David R. Liu, Matthew William Kanan, Mary M. Rozenman
