Nanoparticles too small to see through a traditional microscope could be used in developing therapeutic agents to treat pulmonary disease, and also offer a greater understanding of the health effects of air pollution, according to scientists from HSPH and Beth Israel Deaconess Medical Center. The researchers used a novel, real-time imaging system to track a group of nanoparticles as they moved from the lungs into the body and out again. Akira Tsuda, a co-author and principal research scientist at HSPH, told The Boston Globe that the paper’s findings, published November 7 in an advance online issue of the journal Nature Biotechnology, provided important new information about how nanoparticles interact in the body.
