The anionic fluorosurfactants mainly include perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA), both of which have recently been listed as emerging contaminants and categorised as persistent organic pollutants. This review addresses recent advancements in the development of gold nanoparticle-based nano-sensors for such anions and outlines their performance limitations towards on-site applications.]]> Sat 24 Mar 2018 07:28:26 AEDT ]]> Electrochemical detection of thioether-based fluorosurfactants in Aqueous Film-Forming Foam (AFFF) https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:30591 Sat 24 Mar 2018 07:24:00 AEDT ]]> Surface-enhanced Raman scattering (SERS) detection of fluorosurfactants in firefighting foams https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:24551 via an assembly of dye-FS-AgNP-GO. Using this assembly, we successfully detected FSs including pentadecafluorooctanoic acid (PFOA), perfluorooctanesulfonic acid (PFOS), and 1H,1H,2H,2H-perfluorooctanesulfonic acid (6:2FTS), with a limit-of-detection (LOD) of ~50 ppb (~120 nM) for PFOA.]]> Sat 24 Mar 2018 07:11:30 AEDT ]]>
