摘要
A method of measuring the ability of a biological sample to withstand reactive oxygen species (ROSs). The method includes at least the steps of putting the sample for testing and a photosensitive agent in a liquid medium into contact so as to form a mixture for testing, subjecting the mixture for testing to a dose of light irradiation so as to give rise, by photochemical reaction, to the production of reactive oxygen species, then after irradiation, adding a compound that reacts colorimetrically in the presence of reactive oxygen species (ROSs) to form a chromogen or fluorescent substance, and measuring the quantity of chromogen or fluorescent substance that is produced, and also subjecting a reference mixture to the same photochemical, colorimetric, and measurement reactions as the mixture for testing.
