A nanosensor to predict asthma attacks

A nanosensor to predict asthma attacks

Asthma is a common illness which affects at least 300 million people worldwide and which is responsible for about 200,000 deaths every year. But asthma attacks could be detected up to 3 weeks before they happen by testing regularly the breath of asthmatics. If the levels of nitric oxide increase, an attack might happen soon. Now, researchers at the University of Pittsburgh have created a nanosensor to warn about oncoming attacks. It can be encased into a handheld device that people blow into to determine the nitric oxide content of their breath. These sensors have only been tested in the lab, but human clinical trials are on the way, meaning that they might appear on the market in a few years -- and save lots of lives.
