Researchers use unique molecular signatures to visualize the body

Abstract:
Although scientists understand much about diseases like cancer on a molecular level, imaging diseases still relies largely on anatomy--the outline and shape of a tumor or a clot, for instance. Researchers have been working on ways to visualize molecular changes that take place inside the body, and a new method may offer some advantages over existing anatomical and molecular imaging technologies. In a study published online this week in the Proceedings of the National Academies of Sciences, a team of researchers at Stanford University used Raman spectroscopy, a technique common in chemical analysis, paired with specialized nanoparticles to noninvasively visualize organs and tumors in living mice. The technique could be useful for studying complex disease processes in animals, and, if found to be safe in humans, it could help clinicians view multiple molecular changes in certain cancers and other diseases.
