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. Details of the system were published recently in the online edition of Nature Nanotechnology.
