Researchers from Harvard University's Wyss Institute for Biologically Inspired Engineering have developed a cloaked DNA nanodevice capable of evading the body's immune defenses. The design was inspired by real world viruses and could be used to diagnose cancer and better target treatments to specific areas of tissue.
