(Phys.org)—A diagnosis of pancreatic cancer often means the patient has less than a year to live, and some reports suggest that pancreatic cancer will become the second-leading cause of cancer-related death in the next ...
Molecular probes that selectively latch onto tumor cells and emit imaging signals can detect cancer without invasive procedures. These tools, however, have specific deficiencies. Fluorescent probes that image individual molecules ...
