Nanoparticles in analytical laser and plasma spectroscopy – a review of recent developments in methodology and applications

“…monitoring of the speciation changes of gold-containing nanomaterials in cells). Among others, it has been employed to the study of Au NPs in cytosol, 430 interaction of superparamagnetic iron oxide NPs with proteins, 431 Au NPs and their protein conjugates, 432 Se NPs in human plasma 433 and Ag NPs in complex media (antibiotic and antiseptic liquids, wastewater, etc.). 434 Field-ow fractionation (FFF) separates NPs according to their hydrodynamic diameter and can be used in a range of ca.…”

Atomic spectrometry update: review of advances in the analysis of clinical and biological materials, foods and beverages

“…The results demonstrated the potential for analysing and monitoring the size and concentration of NPs in ultralow-volume blood samples with low concentrations, to show the fate of NPs in vivo . Grønbæk-Thorsen et al 144 also investigated the behaviour of NPs in blood. These authors used CE-ICP-MS to study SeNPs stabilised by a coating of polyvinyl alcohol (PVA).…”

Atomic Spectrometry Update: review of advances in elemental speciation

“…A method based on the use of CE-ICP-MS/MS for detecting SeNPs in aqueous solution and human plasma has been reported. 145 In-house prepared polyvinyl alcohol (PVA) coated SeNPs, synthesised by the reduction of SeO 2 with ascorbic acid, and commercially available SeNPs were used as model nanoparticles in this work. The technical challenge of coupling CE to ICP-MS was solved by the design of an interface consisting of an ES connected to the ICP-MS by an in-house fabricated cap-end.…”
