Doctors experiment with transporting medicine through nanotubes using rocket fuel. This works by storing healing meds with platinum-coated metal tubes; propelling tiny vessels up to 200 times their own length per second. Reacting platinum by putting in a hydrogen peroxide/water solution. Even though the reaction is only .25% peroxide, it's still slightly toxic so it's not ready to be put into humans quite yet.
