A tiny self-propelled drug-delivery device might someday make taking antibiotics safer and more efficient. Think of it as a tiny submarine scooting around inside your stomach, fueled by the acid there.
Oral antibiotics are commonly prescribed life-saving drugs. Once an antibiotic is swallowed, it takes a trip to the stomach, where there's lots of acid. That stomach acid can break chemical bonds in the antibiotic and deactivate it.
