Abstract: The present invention relates to a method for measuring reactive oxygen species generated by nanoparticles. A reactive oxygen species production reaction is performed by radiating light sources after injecting a reactive oxygen species probe material into nanoparticle suspension. The ionic strength of the nanoparticle suspension is enhanced by adding ion sources. At this time, the ion sources may have at least 50mM ionic strength. After the nanoparticles are separated from the suspension through natural sedimentation or centrifugation, absorbance is measured using a detector.

Abstract: 나노입자로부터생성되는활성산소종의측정방법으로, 나노입자현탁액에활성산소종탐침물질을주입한후, 광원을조사하여활성산소종생성반응을진행시킨다. 이어이온공급원을첨가하여나노입자현탁액의이온강도를높인다. 이때, 상기이온공급원은 50mM 이상의이온강도를가질수 있다. 그리고자연침전또는원심분리를통해현탁액으로부터나노입자를분리한뒤, 검출기를이용하여흡광도를측정한다.
