Although a relatively new material, graphene has made considerable impact within the field of electrochemistry and plasmonics.1,2 In the sensing area, the choice of the way graphene is obtained is crucial and will influence strongly electron transfer rates, the shape and position of plasmonic bands but will also impact on sensitivity and selectivity to solution analyst. Beside careful functionalization of graphene, emphasis has to be put on the optimization of the interface design. The majority of electrochemical sensors are produced by simple drop casting with a reduced graphene oxide (rGO) suspension, a method far away from a carefully designed electrode with an optimal structure.

In this presentation, different strategies for the formation of graphene and rGO coated interfaces in a controlled and easy accessible manner will be discusses. A special focus will be on the use of electrophoretic based approaches for the deposition of rGO and hybrid materials.2,3 The use of such interfaces for electrochemical and optical sensing applications will be presented.

Speaker information

Professor Sabine Szunerits, Institut de Recherche Interdisciplinaire. Professor Szunerits has been at the University of Lille since September 2009 (Theoretical chemistry, physics, analytical) Sabine Szunerits is part of the Interdisciplinary Research Institute ( IRI ). She is involved within the team investigating Nanobiointerfaces led by Rabah Boukherroub. Her research consists of connecting a controlled surface chemistry, surface structuring across the micron and nanometer and the study of biomolecular interactions at the molecular level in four major areas of research: 1. Development of new plasmonic interfaces; 2. Nanostructured surfaces hydrogenated boron-doped diamond for applications in biosciences; 3. Functionalisation metal nanoparticles (eg Au, Ag) and semiconductors (eg Si, diamond); 4. Corrosion / biocorrosion: protection of metals and semiconductors with superhydrophobic films or thin films.
