Graphene sensor rapidly detects opioid metabolites in wastewater

The unique properties of the atom-thick sheet of carbon, known as graphene, enabled a new penny-sized, multiplexed bio-sensor that's the first to detect opioid byproducts in wastewater, a team of researchers from Boston College, ...

Innovative sensor specifically and precisely detects molecules

Researchers of Karlsruhe Institute of Technology (KIT) and Technical University of Darmstadt have developed a novel sensor for gas molecules by combining a graphene transistor with a customized metal-organic coating. The ...

'Bite' defects revealed in bottom-up graphene nanoribbons

Graphene nanoribbons (GNRs), narrow strips of single-layer graphene, have interesting physical, electrical, thermal, and optical properties because of the interplay between their crystal and electronic structures. These novel ...

A new all-2-D light-emitting field-effect transistor

Transition metal dichalcogenides (TMDs), a two-dimensional (2-D) semiconductor, are promising materials for next-generation optoelectronic devices. They can emit strong light due to the large binding energies of excitons, ...
