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.
