DNA nanorobots find and tag cellular targets
August 7, 2013
Researchers have created a fleet of molecular "robots" that can hone 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 cells' surfaces. Details of the system were published July 28, 2013, in the online edition of Nature Nanotechnology.
