Frog foam could deliver drug therapy

Foam made by miniature frogs to protect their eggs could offer a clever way to deliver healing drugs to burns patients, say scientists.

Tough bubbles could trap and deliver medication while providing a protective barrier between the wound dressing and the damaged skin, they believe.

The Strathclyde University researchers have begun making a synthetic version of foam.

They are taking inspiration from the tiny Tungara frog from Trinidad.

After mating, the 5cm-sized amphibians whip up a bubbly nest that protects the spawn for days from disease, predators and weather.
