Dots Pinpoint Cancer
Researchers from MIT’s Department of Chemistry and two Boston hospitals - Beth Israel Deaconess Medical Center and Brigham and Women’s - recently tested a method that could simplify exploratory cancer surgery for both surgeons and patients. The researchers used semiconducting particles, called quantum dots, to illuminate specific lymph nodes in test animals. The technique could allow surgeons to “see” lymph nodes before they begin surgery.
