Which Came first ? The GFN's or the Corona ?

Toxicity of graphene-family nanoparticles

GFNs can induce acute and chronic injuries in tissues by penetrating through the blood-air barrier, blood-testis barrier, blood-brain barrier, and blood-placenta barrier etc. and accumulating in the lung, liver, and spleen etc.

For example, some graphene nanomaterials aerosols can be inhaled and substantial deposition in the respiratory tract, and they can easily penetrate through the tracheobronchial airways and then transit down to the lower lung airways, resulting in the subsequent formation of granulomas, lung fibrosis and adverse health effects to exposed persons

nanomaterials can easily form “coronas” with proteins in biological systems. The protein corona is suggested to affect the circulation, distribution, clearance and toxicity
