Traveling Light

Using different sized fluorescent quantum-dot nanoparticles, scientists at Harvard’s School of Public Health and Beth Israel Deaconess Medical Center were able to follow the particles in rats with near-infrared imaging through the lungs and into the blood stream, noting differences in speed by size, shape and surface charge.  In effect, this was simulated pollution, but the findings have potential value for future drug delivery strategies.          MORE
