Reference Origin/Type of NP Animal Specie Route of administration Results
[39] Inorganic Mice Oral NP abrogated the diabetes-induced embryopathy through your antioxidant effects.
Mettalic
Cerium
[43] Inorganic Mice Oral NP caused toxicity to fetus.
Mettalic
ZnO
[45] Organic Ratss Intravenous NP prevented oxidative stress in placenta, but not in the fetus.
Polymeric
Poly (γ-glutamic acid) and l-phenylalanine ethylester
[46] Organic Rats Intravenous NP caused beneficial effects dependent on sex and age on the cardiovascular function of adult offspring.
Polymeric
Poly (γ-glutamic acid) and l-phenylalanine ethylester
[48] Inorganic Mice Oral NP caused a decrease in angiogenesis and activation of apoptotic pathways through caspase-3 in placental tissue.
Mettalic
TiO2
[50] Organic Mice Oral NP improved the delivery of compound to the maternal and fetal brains and also reduced the accumulation of fatty acids in fetal liver.
Protein
Zein
[55] Inorganic Rats Intraperitoneal NP had a toxic effect on maternal, placenta and fetus tissues.
Mettalic
Ag coated with chitosan
[57] Inorganic Rats Inhalation NP caused severe impacts causing fetal resorption, decreased estrogen and increased proinflammatory cytokines levels.
Mettalic
Ag
[59] Organic Rats Intravenous There was a tissue distribution depending on the particle charge.
Polymeric
Poly (glycidyl methacrylate)
[68] Inorganic
Mettalic
Au
Mice Intravenous There was a tissue distribution depending on the particle size.
[69] Organic Mice Intravenous Np with diameters up to 500 nm were absorbed by placenta and were able to cross the placental barrier.
Polymeric
Polystyrene
[70] Inorganic Mice Intravenous In clinical and histopathological evaluation, there were no changes in placental and fetal development.
Mettalic
SiO2
[71] Inorganic Mice Subcutaneous Maternal exposure to NP influenced the offspring central dopaminergic system.
Mettalic
TiO2
[72] Organic Mice Intravenous Prevented fetal exposure and minimized placental exposure.
Liposome
Phosphatidylcholine + cholesterol
[73] Inorganic Mice Intravenous Remarkable accumulation of silver in maternal liver and spleen, may have affected embryonic growth.
Mettalic
Ag
[74] Inorganic Rats Oral NP induced oxidative stress and apoptosis in the fetal liver.
Mettalic
Ag
[75] Inorganic Chicken Oral NP caused abnormal expression of genes and proteins in offspring liver.
Mettalic
ZnO
[76] Organic Polymeric Poly(ϵ-caprolactone) Rats Oral NP did not cause toxicological effects in pregnant rats and your fetuses.
