Determination of particle size and number concentrations in gold nanoparticle mixtures: an inter-method study using four analytical techniques (DLS, PTA, SEM and spICP-MS)
Birgit Hetzer, Alexandra Müller, Ann-Katrin Meinhardt, Volker Gräf, Elke WalzReliable fraction-resolved analysis of particle size and number concentration of multimodal gold nanoparticle mixtures (30–100 nm) requires complementary methods. In this inter-method study, spICP-MS provided the most comprehensive information.
