Research output: Contribution to journalArticlepeer-review


Scanning electrochemical microscopy (SECM) can image graphene oxide (GO) flakes on insulating and conducting substrates. The contrast between GO and the substrate is controlled by the electrostatic interactions that are established between the charges of the molecular redox mediator and the charges present in the sheet/substrate. SECM also allows quantitative measurement-at the nano/microscale-of the charge transfer kinetics between single monolayer sheets and agent molecules. This journal is
