Separation of silver nanoparticles with different coatings by capillary electrophoresis coupled to ICP-MS in single particle mode
D Mozhayeva, C Engelhard - Analytical chemistry, 2017 - ACS Publications
The possibility of separating mixtures of Ag nanoparticles (NPs) with similar sizes but
different surface coatings using capillary electrophoresis coupled to single particle
inductively coupled mass-spectrometry (CE-SP-ICP-MS) was investigated. In two-
component mixtures, it was possible to separate 40 nm sized polyvinylpirrolidone (PVP)-and
citrate-coated NPs, 40 nm sized polyethylene glycol (PEG)-and citrate-coated NPs, and 60
nm sized PVP-and citrate-coated NPs. The separation of a more complex mixture containing …
