Andrew J. Turberfield has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Molecular electronic device
    Patent number: 11653566
    Abstract: A molecular electronic device (10) includes a framework of polynucleotides (3), one or more molecular electronic components (4) and one or more electrical contacts (7). The molecular electronic components and the electrical contacts are each connected to the plurality of polynucleotides such that the molecular electronic components and the electrical contacts are located with respect to the framework and with respect to each other. This forms a coupling between the electrical contacts and the molecular electronic components.
    Type: Grant
    Filed: June 5, 2019
    Date of Patent: May 16, 2023
    Assignee: OXFORD UNIVERSITY INNOVATION LIMITED

  • Engineered toehold reactions and networks
    Patent number: 8110353
    Abstract: A catalytic system and method of catalyzing reactions that uses a novel toehold exchange mechanism that allows a specified input to catalyze the release of a specified output, which in turn can serve as a catalyst for other reactions is provided. This toehold exchange catalyst system, which can be driven forward by the configurational entropy of the released molecule, provides an amplifying circuit element that is simple, fast, modular, composable, and robust. Using this toehold exchange catalyst system it has been possible to construct and characterize several circuits that amplify nucleic acid signals, including a feed-forward cascade with quadratic kinetics and a positive feedback circuit with exponential growth kinetics.
