The colorimetry and smartphone determination of perfluorooctane sulfonate based on cytidine 5′-monophosphate-capped gold nanoclusters with peroxidase-like activity

/TMB to PFOS was extended to smartphone determination conveniently based on RGB values. Finally, the established platform was applied to PFOS determination both in soil extracts and in tap water with good recovery, which supplies a novel colorimetric platform for visual determination of PFOS in practice. The method has the advantages of being rapid, sensitive and highly selective, which highlight the design and construction of more systems for determination and elimination of lethal pollutants in environmental water.
