Scientist chronicle nanoparticles' journey from the lungs into the body

Using a novel, real-time imaging system, scientists have tracked a group of near-infrared fluorescent nanoparticles from the airspaces of the lungs, into the body and out again, providing a description of the characteristics and behaviour of these minute particles which could be used in developing therapeutic agents to treat pulmonary disease, as well as offering a greater understanding of the health effects of air pollution...
