Spotting a single cancerous cell that has broken free from a tumor and is traveling through the bloodstream to colonize a new organ might seem like finding a needle in a haystack. But a new imaging technique from the University of Washington is a first step toward making this possible. UW researchers have developed a multifunctional nanoparticle that eliminates the background noise, enabling a more precise form of medical imaging "“ essentially erasing the haystack, so the needle shines...

Nanoparticles are being developed to perform a wide range of medical uses -- imaging tumors, carrying drugs, delivering pulses of heat. Rather than settling for just one of these, researchers at the University of Washington have combined two nanoparticles in one tiny package.The result is the first structure that creates a multipurpose nanotechnology tool for medical imaging and therapy. The structure is described in a paper published online this week in the journal Nature...
