Abstract Graphene has unique mechanical, electronic, and optical properties, which researchers have used to develop novel electronic materials including transparent conductors1,2 and ultrafast transistors, etc. Recently, understanding various chemical and optoelectronic properties of graphene has facilitated its application to high-performance devices that generate or store energy. Graphene is now expanding its territory beyond display/energy applications and moves toward biomedical research areas.3 In this talk, recent advances in the industrial production of CVD graphene films will be reviewed first, and novel chemical phenomena in 2-dimension enabled by the unique properties of graphene will be discussed, including graphene catalyzed/inhibited reactions,4 in-situ observation of 2D liquids in graphene liquid cell,5 unusual stability of biological samples under graphene layers,6 and novel optical/chemical behaviors of molecules between graphene layers.
