Viral Membrane Protects Medical Nanorobots From Immune System

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 at Harvard’s Wyss Institute for Biologically Inspired Engineering have been able to construct their own version of a viral membrane.
