Intranasal exposure to amorphous nanosilica particles could activate intrinsic coagulation cascade and platelets in mice

摘要

BackgroundNanomaterials with particle sizes <100 nm have been already applied in various applications such as cosmetics, medicines, and foods. Therefore, ensuring the safety of nanomaterials is becoming increasingly important. Here we examined the localization and biological responses of intranasally administered amorphous nanosilica particles in mice, focusing on the coagulation system.
