Perfusion kinetics and placental tissue accumulation of Au-3-PEG and Au-4-COONa NPs determined by SF-ICP-MS. a Maternal and fetal AuNP concentration over time (data presented as mean ± SD). AuNP concentrations were calculated from the Au concentrations measured with SF-ICP-MS using the relative Au content of the NPs determined with ICP-OES (see Table 1). b Placental tissue accumulation of Au-3-PEG and Au-4-COONa NPs after 5–6 h of perfusion, shown as Au and AuNP concentration (calculated as indicated before)
