Patents by Inventor Kristian A. Roth

Kristian A. Roth 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).

  • Open circuit potential amperometry and voltammetry
    Patent number: 7826250
    Abstract: This invention provides approaches to improve the signal to noise ratio (S/N) in electrochemical measurements (e.g., amperometry, voltammetry, etc.). In particular, a method is described wherein the faradaic current is temporally dissociated from the charging current associated with reading the charge of a redox-active species (e.g., a self-assembled monolayer (SAM)). This method, designated herein as open circuit potential amperometry (OCPA), quantitatively reads the charge of the redox species bound to (electrically coupled to) an electrode surface, while discriminating against both charging current(s) and amperometric signal(s) that arise, e.g., from diffusion-based species in solution.
    Type: Grant
    Filed: April 7, 2005
    Date of Patent: November 2, 2010
    Assignee: North Carolina State Univeristy
    Inventors: Werner G. Kuhr, David F. Bocian, Jonathan S. Lindsey, Kristian A. Roth
