Nanoparticles, microscopic particles with at least one dimension less than 100 nm, are a part of everyone’s daily life. You don’t have to be involved in their manufacture to be exposed to nanoparticles. Walking down the street we are exposed to vehicle exhaust (man-made nanoparticles); while on vacation at the beach everyone has come in […]
