Nanoscale Sensor Provides Clear Optical Fingerprint to ID Pollutants

Facebook Twitter LinkedIn Email
A sensor made with ultrathin nanomaterials could improve environmental sensing by providing an unambiguous optical fingerprint for the detection of molecules. Traditional sensors rely on small peak shifts and intensity changes, a less precise approach to identifying molecules in the air. A research team from Chalmers University of Technology and Technische Universität Berlin developed the highly efficient sensor using atomically thin transition metal dichalcogenides (TMDs). The material’s optimal surface-to-volume ratio, combined with strong light-matter interaction, makes it...Read full article
