Washington Devises Microneedles for Painless, Easy-to-Use TB Skin Test

A team from the University of Washington has created tiny, biodegradable needles for diagnosing tuberculosis that promise to be easier to use, more accurate, and less painful than hypodermic needles. The microneedles, applied by skin patch, are like putting on bandages and may be more successful with young children afraid of needles, researchers say. The microneedles are made of chitin, a tough but biodegradable material found in the hard outer shells of some insects and crustaceans – in this case, squid.
