Nanoparticles

Do immature lungs have air–blood barriers that are more permeable to inhaled nanoparticles than those of fully developed mature lungs?

A recent collaborative study between Harvard and UC Davis produced data backing the notion that nanoparticles (NP) more frequently crossed the air-blood lung barrier to the rest of the body in infant rats than adults. Fascinatingly, this higher permeability demonstrates immature lungs do not follow the same directives as mature lungs.
