Nanotechnologies. Testing the photocatalytic activity of nanoparticles for NADH oxidation1 Scope 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.
