  • Reactive oxygen species measuring device
    Patent number: 8298387
    Abstract: A reactive oxygen species measuring device according to the present invention comprises a reactive oxygen species sensor provided with an electrode assembly capable of detecting the presence of reactive oxygen species or the like in terms of an electric current, a power source means for applying a measuring voltage to the reactive oxygen species sensor, and a reactive oxygen species concentration measuring means for measuring a concentration of the reactive oxygen species or the like from the current detected by the reactive oxygen species sensor. According to the present invention, a concentration of reactive oxygen species or the like such as in vivo or in vitro superoxide anion radical (O2?.) can be measured reliably, and the entire device can be formed in a smaller size and always mounted to a living body.
    Type: Grant
    Filed: February 24, 2004
    Date of Patent: October 30, 2012
    Inventors: Makoto Yuasa, Fumio Mizoguchi, Hitoshi Takebayashi, Masahiko Abe, Masumi Koishi, Shigeru Kido, Masamitsu Nagahama, Masayuki Kawasaki, Masahiko Yokosuka, Takashi Ishihara, Rizwangul Ibrahim
