Chemists develop noselike sensor array to 'smell' cancer diagnoses

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 have developed a rapid, sensitive way to detect microscopic levels of many different metastatic cell types in living tissue. Researchers used a sensor array system of gold nanoparticles and proteins to "smell" different cancer types in much the same way our noses identify and remember different odors.
