Working on the frontier of nanoparticle research

A field studying something very small is becoming very big: In the last decade, the field of nanoparticle research has exploded. At about one nanometer in size, nanoparticles are 100,000 times smaller than the width a strand of human hair and cannot be seen with the naked eye, but researchers are discovering broad uses for them in fields ranging from bioimaging to energy and the environment.
