    Gold nanoparticles (at left) with green fluorescent protein (GFP) 'smell' different cancer types in much the same way our noses identify and remember different odors. At right, the distinct protein levels in a cancer interact with the particle to generate patterns used to identify cancer type. Credit: UMass Amherst

    In the fight against cancer, knowing the enemy's exact identity is crucial for diagnosis and treatment, especially in metastatic cancers, those that spread between organs and tissues. Now chemists led by Vincent Rotello at the University of Massachusetts Amherst have developed a rapid, sensitive way to detect microscopic levels of many different metastatic cell types in living tissue. Findings appear in the current issue of the journal ACS Nano.
