Cheap blood test detects pancreatic cancer before it spreads
The deadly cancer is often not found until it has spread to other parts of the body.
“It’s a very pragmatic, really translatable solution,” that builds on many advances in the field, says Simone Schürle-Finke, a biomedical engineer at Swiss Federal Institute of Technology (ETH) in Zurich, Switzerland. “There is a huge need for developing new ways of detecting pancreatic cancer early,” says study co-author Jared Fischer, a molecular biologist at Oregon Health & Science University (OHSU) in Portland. To detect the presence of these proteases in the blood, the researchers developed nanosensors containing a magnetic nanoparticle, attached to a small peptide that attracts matrix metalloproteinases and a fluorescent molecule.
