Wolverine is a mutant and because of that, he never has to worry about getting sick. For the rest of us, disease and illness can turn the strongest brute into a baby. Although medicines such as antibiotics help, they are reaching their limits. Bacteria evolve new ways to elude drugs and render them ineffective. Nanotechnology could offer a unique way to battle these bacterial villains.
Researchers in DARPA's "Rapidly Adaptable Nanotherapeutics" are creating therapeutic nanoparticles to target genetically engineered bioweapons. The idea is to inject tiny, autonomous drug-delivering particles into a person's bloodstream and have those particles deliver molecules of medication anywhere in the body. The "medicine" would be comprised of molecules designed to target and shut down specific genes that would normally be affected by toxins.
