A Sensor to Take Your Breath Away
Early-stage lung cancer, one of the most common and aggressive cancers, kills around 1.4 million people worldwide every year – so the pursuit of new techniques to accurately detect it remains a global challenge. Now, a highly sensitive graphene biosensor has shown potential in electronic nose devices, which analyze the components of vapor mixtures such as breath. Multi-layered graphene can detect biomarkers selectively and sensitively, providing hope that a cheap, reusable, and accurate breath test for early-stage lung cancer could become a reality (1).
