An example of the risk posed by nanomaterials is sunscreen. Dermal penetration of some nanomaterials into the skin can potentially pose a hazard to human health...

Nanoparticles Impair Blood Vessel Function

Prior posts have noted the wide range of materials and consumer products in which nanoparticles are used, and also that nanoparticles can cross the so-called blood-brain barrier. New research, using animal models, suggests that such materials may impair blood vessel function. Researchers exposed rats...
