CWRU Researchers Make Biosensor 1 Million Times More Sensitive

Physicists and engineers at Case Western Reserve University have developed an optical sensor that’s 1 million times more sensitive than the current best available—one capable of identifying a single lightweight molecule in a highly dilute solution. Their goal is to provide oncologists a way to detect a single molecule of an enzyme produced by circulating cancer cells, allowing doctors to diagnose patients with certain cancers far earlier than possible today, and improve treatment and outcomes.
