Graphene is a unique two-dimensional (2D) structure of monolayer carbon atoms packed into a dense honeycomb crystal that has attracted great interest due to its diverse and fascinating properties.

Since its discovery little more than a decade ago,1 the two-dimensional (2D) allotrope of carbon—graphene—has been the subject of intense multidisciplinary research efforts.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
