(CNN) -- They're ready to sting, and they know where they're going.
They're called "nanobees," and they're not insects -- they're tiny particles designed to destroy cancer cells by delivering a synthesized version of toxin called melittin that is found in bees.
"Melittin, which would otherwise result in substantial destruction of your red ***** cells and other normal tissues if it were delivered intravenously alone, is completely safe when it's on a nanoparticle," said Dr. Samuel Wickline, director of the Siteman Center of Cancer Nanotechnology Excellence at Washington University in St. Louis, Missouri.
