Yoshihito Ikariyama 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).

  • Light emitting method of acridinium derivative and method of detecting substance to be examined using same
    Patent number: 5879888
    Abstract: A light emitting method of an acridinium ester, comprising reacting said acridinium ester and a superoxide anion, and a method of detecting a substance to be examined, comprising detecting a light emitted by reacting a superoxide anion with an acridinium ester used as a label are described. It is possible to carry out the reaction not under strongly alkaline conditions but around the neutral point and to generate strong luminescence which is stable over a long period of time.
    Type: Grant
    Filed: October 30, 1996
    Date of Patent: March 9, 1999
    Assignee: Iatron Laboratories, Inc.
    Inventors: Masuo Aizawa, Yoshihito Ikariyama, Eiry Kobatake, Minoru Ogasawara, Mitsunao Tanaka
  • Method of immobilizing biofunctional material, and element prepared thereby, and measurement by using the same element
    Patent number: 5256271
    Abstract: A microbioelectrode having high performance produced by immobilization by incorporating a biologically active substance in the interior or on the surface of a porous conductive material layer or fine particle layer which has been deposited on the surface of a transducing material. The inventive microbioelectrode demonstrates sufficient output even if the sensor using the electrode is very small in size.
