本文件规定了一种通过测量紫外线（UV）诱导的尼古丁腺嘌呤二核苷酸水合物（NADH）氧化来测量悬浮在水环境中生理相关条件下的纳米颗粒（NPs）光催化活性（PCA）的方法。该测量旨在评估纳米材料光毒性的可能性。该方法也适用于NP骨料和团聚体。

This document specifies a method for the measurement of the photocatalytic activity (PCA) of nanoparticles (NPs), suspended in an aqueous environment in physiologically relevant conditions, by measuring the ultraviolet (UV)-induced nicotine adenine dinucleotide hydrate (NADH) oxidation.The measurement is intended to assess the potential for the photo-toxicity of nanomaterials. The method is also applicable to NP aggregates and agglomerates.
