Nanotechnologies — Testing the photocatalytic activity of nanoparticles for NADH oxidation (ISO 20814:2019)
This document specifies a method for the measurement of the photocatalytic activity (PCA) ofnanoparticles (NPs), suspended in an aqueous environment in physiologically relevant conditions, bymeasuring the ultraviolet (UV)-induced nicotine adenine dinucleotide hydrate (NADH) oxidation.The measurement is intended to assess the potential for the photo-toxicity of nanomaterials. Themethod is also applicable to NP aggregates and agglomerates.
