Virus Inspired DNA Nanodevices
Scientists say they have developed a cloaking device to spirit medical nanorobots of the future past immune systems into diseased cells. Their innovation comes from stealing a powerful weapon viruses wield to infect their hosts.
Some viruses wrap themselves in a protective membrane to avoid detection by their host’s immune system and enter cells they are trying to infect. A team of scientists at Harvard's Wyss Institute for Biologically Inspired Engineering have mimicked these viral tactics to build the first DNA nanodevices that survive the body's immune defenses.
The results pave the way for smart DNA nanorobots that could use logic to diagnose cancer earlier and more accurately than doctors can today; target drugs to tumors, or even manufacture drugs on the spot to cripple cancer, the researchers report in the April 22 online issue of ACS Nano.
