Scientists have devised a triple-stage stealth “cluster bomb” system for delivering the anti-cancer chemotherapy drug cisplatin, using nanoparticles designed to break up when they reach a tumor:

  1. The nanoparticles start out relatively large  — 100 nanometers wide — so that they can move through the bloodstream and smoothly transport into the tumor through leaky blood vessels.
  2. As they detect acidic conditions close to tumors, the nanoparticles discharge “bomblets” just 5 nanometers in size to penetrate tumor cells.
