TLDR
Pregnant mice treated with 70-nm silica nanoparticles or 35-nm titanium dioxide nanoparticles suffer damage to the placenta and fetus, whereas larger nanoparticles do not have an adverse impact.

Inhaled Nanoparticles Accumulate at Sites of Vascular Disease

TL;DR: Translocation of inhaled nanoparticles into the systemic circulation and accumulation at sites of vascular inflammation provides a direct mechanism that can explain the link between environmental nanoparticles and cardiovascular disease and has major implications for risk management in the use of engineered nanomaterials.
Journal ArticleDOI

Advances in the application, toxicity and degradation of carbon nanomaterials in environment: A review.

TL;DR: This work systematically describes the toxicity of carbon nanotubes, graphene, GRA and C60 to cells, animals, humans, and microorganisms and has prospects for the limitations of CNM degradation under non-experimental conditions and their potential application.
Journal ArticleDOI

Exocytosis of nanoparticles from cells: Role in cellular retention and toxicity

TL;DR: An overview of how NPs are handled intracellularly and how they are excreted from cells following the uptake is presented and how exocytosis of nanomaterials impacts both the therapeutic delivery of nanoscale objects and their nanotoxicology is discussed.
Journal ArticleDOI

Assessing clinical prospects of silicon quantum dots: studies in mice and monkeys.

TL;DR: It is shown that neither mice nor monkeys show overt signs of toxicity reflected in their behavior, body mass, or blood chemistry, even at a dose of 200 mg/kg, and the formulation did not biodegrade as expected.

Silica and titanium dioxide nanoparticles cause pregnancy complications in mice.

TL;DR: In this paper, the authors showed that nanoparticles with diameters of 70 nm and 35 nm can cause pregnancy complications when injected intravenously into pregnant mice, and that these detrimental effects are linked to structural and functional abnormalities in the placenta on the maternal side, and are abolished when the surfaces of the silica nanoparticles are modified with carboxyl and amine groups.

Barrier Capacity of Human Placenta for Nanosized Materials

TL;DR: The findings suggest that nanomaterials have the potential for transplacental transfer and underscore the need for further nanotoxicologic studies on this important organ system.

Nanoparticles Transferred from Pregnant Mice to Their Offspring Can Damage the Genital and Cranial Nerve Systems

TL;DR: It is shown that nano-sized titanium dioxide (TiO2), which is used widely as a photo-catalyst and in consumer products, administered subcutaneously to pregnant mice is transferred to the offspring and affects the genital and cranial nerve systems of the male offspring.

Novel harmful effects of [60]fullerene on mouse embryos in vitro and in vivo

TL;DR: In vivo and in vitro action of C60 on embryogenesis is a novel and seriously harmful activity, although weaker than the vehicle controls.
