One of the challenges of fighting pancreatic cancer is finding ways to penetrate the organ's dense tissue to define the margins between malignant and normal tissue. A new study uses DNA origami structures to selectively deliver fluorescent imaging agents to pancreatic cancer cells without affecting normal cells. The study, led by mechanical science and engineering professors found that specially engineered DNA origami structures carrying imaging dye packets can specifically target human KRAS mutant cancer cells, which are present in 95% of pancreatic cancer cases.
