About this collection

To coincide with the 15th year since graphene was first reported, Andrea Ferrari (University of Cambridge and Nanoscale Associate Editor) has picked out his top articles that were recently published in the nanoscale journal family. Focusing specifically on the bio-implications and bio-applications of graphene, this Editor’s Choice collection highlights some of the key recent advances in the field.

Professor Dirk Guldi, Friedrich-Alexander-Universität Erlangen-Nürnberg, Germany and Editor-in-chief of Nanoscale and Nanoscale Advances: “The outstanding properties of graphene have been a jump start for cutting-edge research in the areas not only of physics, chemistry, materials science but also of life science.  Hereby, graphene and its 2-dimensional analogues have transcended into a versatile and enabling platform for those multidisciplinary breakthroughs needed to lay the foundation for a myriad of applications.”

Professor Paolo Samori, Université de Strasbourg and Associate Editor for Nanoscale and Nanoscale Advances: “Over the last 15 years, graphene and related materials became the "golden" nanostructures for fundamental studies on their exceptional and physical and chemical properties. The interdisciplinary science of 2D materials has led to major breakthroughs paving the way towards disruptive technologies in opto-electronics, energy, sensing and biomedical applications.”

Andrea Ferrari is also the Science & Technology Officer and Management Panel Chair of the Graphene Flagship, which also celebrated graphene turning 15 this year.
