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 optical communications gain speed

Optical communication formed the backbone of the internet age and is expected to be equally pivotal for the developing 5G networks. Modern communications rely on optical links that fly information at the speed of light, and on circuitry such as photodetectors and modulators which is able to encode a wealth...

Terahertz communications circuits inch closer with graphene isolator

Graphenea's graphene has been used to make an optical isolator, an important component of optical communication circuits, in the terahertz part of the spectrum. Terahertz communication circuits would boast wireless transmission rates 10 times faster than they are today. Scientists in Switzerland constructed a graphene-based device that transmits light only...

Electrical control of light emission near graphene

Marko Spasenovic

Controlling the energy emission of light sources is of fundamental interest and has many applications in photovoltaics, quantum optics, photodetection, biosensing, and other fields. In one of our most recent papers, team Graphenea together with collaborators from Spain, France, Italy, and the USA has demonstrated electrical control of the flow...
