ISO 20814 discusses nanotechnologies. ISO 20814 is an international standard for testing the photocatalytic activity of nanoparticles in nanotechnologies.
ISO 20814 outlines 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 under ISO 20814 also applies to NP aggregates and agglomerates.
ISO 20814 on testing the photocatalytic activity of nanoparticles for NADH oxidation is useful for:
Photocatalytic activity (PCA) is the measure of the capacity of a material to promote a specific photochemical reaction under defined conditions (as defined in ISO 20507:2014, 2.3.31). With the expanding use of nanomaterials in various industries, the possible impacts on human health and the environment due to the enhancement of detrimental chemical reactions in the presence of light (both natural and artificial) is an ongoing concern.
ISO 20814 guidelines assist you with the measurement of NP suspension basic properties, UV trans-illuminator light intensity calibration based on 2NB actinometry, and measurement of NADH solution fluorescence intensity for testing the photocatalytic activity of nanoparticles for NADH oxidation.
ISO 20814 assist in the proper assessment of photocatalytic activity of nanoparticles for NADH oxidation and provides reliable results that are comparable to other laboratories.
