Graphene Biosensors

A biosensor is a device which measures biological or chemical reactions by creating an electrical output response that is proportional to the concentration of a particular substance (or analyte) within that reaction. They are used in a wide range of areas including medical treatment, environmental surveys, food control, forensics and...

Graphene for catalysis

Marko Spasenovic

Catalysis plays a major role in today’s society, impacting an estimated 90% of all commercially produced chemical products. Generating about a trillion USD in products worldwide, catalysis is used in energy processing (petroleum refining, steam reforming, automotive catalytic conversion, fuel cells), bulk and fine chemical manufacturing, food processing, and environmental...

Graphene senses opioids, desalinates water, and generates electricity

Marko Spasenovic

Generating electricity, desalinating water, and sensing trace chemicals are some of the uses of graphene just added to the growing list of this material's potential applications. They all feature graphene in a liquid environment, where one wouldn't expect it due to its hydrophobic nature. Research at the University of Pennsylvania,...

CVD graphene suitable for transistors and surface chemistry studies

Marko Spasenovic

With exceptional carrier mobilities, mechanical strength, and optical transparency, graphene is a leading material for next-generation electronic devices. However, for most applications, graphene will need to be integrated with other materials, which motivates efforts to understand and tune its surface chemistry. In recent work, published in the scientific journal Small,...
