The magic, it turns out, is in that subatomic spray, as the group treated with an electron shower benefited from a polymerizing effect or, more plainly, a bonding of molecules just above the skin's surface that yielded a tough, protective nano-layer measuring between 50- to 100-billionths of a meter thick.
