Researchers at Columbia University Medical Center, working with their collaborators at the Hospital for Special Surgery, have created a fleet of molecular “robots” that can home in on specific human cells and mark them for drug therapy or destruction.
The nanorobots—a collection of DNA molecules, some attached to antibodies—were designed to seek a specific set of human blood cells and attach a fluorescent tag to the cell surfaces.
