Graphene carbon atoms packed in a honeycomb lattice exhibits exceptional physical and electronic properties not found in conventional materials. Decorating the surface of graphene with nanoparticles may further enhance the performance of the material, but the fabrication technique is not without its challenges. Verawati Tjoa and co-workers at the A*STAR Singapore Institute of Manufacturing Technology and Nanyang Technological University have now demonstrated an easy way to decorate the surface of graphene with gold nanoparticles. The resulting material is more sensitive and versatile than undecorated graphene for gas detection.
