Table 4 MPs on placentas
Sample type | Size | Effects | Reference |
|---|---|---|---|
carboxylated polystyrene spheres (PS25C) | 25 nm | Nanoscale PS magnetic nanoparticles (MNPs) have the ability to penetrate the intestinal barrier, allowing them to subsequently traverse the maternal-fetal barrier of the placenta. This enables access to the fetal circulation and all fetal tissues | [68] |
MPs PP | rom 5 to 10 μm | MPs were found in 4 of 6 placentas | [67] |
PS nanoparticles | 80 nm | the protein corona formed by human albumin significantly induced the transfer of MPPSs across the placenta | [66] |
COOH-modified PS | 50 nm - 0.5 μm | Intestinal and placental cellular uptake and intracellular accumulation of MNPs and MPs of PS | [65] |
