The imbalance between oxidants and antioxidants in biological systems may lead to oxidative stress, which is associated with the pathogenesis of several human diseases. The putative protective effects of antioxidants against these oxidative-induced reactions have received increasing attention. Here, the concept of oxidative stress is introduced, including reactive oxygen species, antioxidants, oxidative injury, etc. Furthermore, the methods most widely used for the determination of reactive oxygen species/reactive nitrogen species scavenging capacity as well as the newly developed evaluation assay using gold nanoshells composites by our research group and other methods based on nanomaterials are evaluated, presenting the general principles, recent applications, and their strengths and limitations. Finally, current problems and the prospect of the standardized analytical methods are proposed.
