Document Title:Nanotechnologies — Testing the photocatalytic activity of nanoparticles for NADH oxidation
url:
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.

Keywords:Photocatalytic activity; titanium dioxide, environmental media, phototoxicity
Type of Document:a. Standard
Issues Areas:Health, Safety, and Environment
Primary Category:Chemicals e.g. pesticides, pharmaceuticals, paints, basic chemicals
Additional Categories
Goal or Need:Oxidative stress is an established nanoparticle toxicology mechanistic paradigm
Intended Stakeholders:Nanomaterial manufacturers, nanomaterial users (cosmetics, pharmaceuticals, composite material, food packaging producers), testing laboratories, regulatory agencies.
