Patents by Inventor Noboru Fukasaku

Noboru Fukasaku 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).

  • Electron mediator, electron mediator immobilized electrode, and biofuel cell using the electrode
    Patent number: 7544438
    Abstract: An object of the present invention is to provide a highly functional mediator capable of smoothly proceeding electron transfer between an electrode and a biocatalyst based on the premise that the mediator excels in safety and cost and to provide an electrode and a cell with sufficient amount of such a mediator molecule immobilized efficiently and strongly. The present invention provides a mediator mediating electron transfer between an enzyme and an electrode and containing a quinone molecule derivative, in particular, a mediator containing a VK3 derivative. In addition, the present invention provides an electrode and a biofuel cell to which those mediators are applied.
