Scope

This document describes a method for measuring the photocatalytic activity of nanoparticles. The method involves suspending nanoparticles in aqueous solutions relevant to the physiological environment and measuring the oxidation of reduced nicotinamide adenine dinucleotide (NADH) induced by UV light irradiation.
This document is applicable to the evaluation of the phototoxicity of nanomaterials, as well as to nanoparticle aggregates and agglomerates.
