ITODYS (Interface, Treatment, Organization and Dynamics of Surfaces) is an academic laboratory belonging to University Paris Diderot (UPD) and to CNRS (UMR 7086). ITODYS is a multidisciplinary laboratory dealing with fundamental research in chemistry for nanosciences, with a particular attention for surface sciences, nanomaterials, nanosystems and molecular chemistry. The laboratory gathers the complementary skills of 49 permanent researchers, 18 technical and administrative staff and 35 PhD students, specialists of surfaces functionalization, nanomaterials and molecular electronics. Three main domains of research are developed, based on current fundamental questions and technological applications in the fields of materials science, nanoscience and nanotechnology. The laboratory is structured around three scientific departments: D1 “Surfaces, Nanostructuration and reactivity”, D2 “Nano-objet: chemistry, physics and application” and D3 “Molecular electronics, transduction and nanoelectrochemistry”, a molecular modeling group and a technical department. Several experimental questions such as electronic structure of pi-conjugated systems or surface chemistry are addressed by the molecular modeling group using molecular mechanics and quantum chemistry methodologies.


The group which is active in this project is SBC  (Bioactives Surfaces and Sensors), of 7 senior researchers. Among them, 4 are involved in this project (one chemist, two electrochemists, one physicist). SBC has an integrative approach of surfaces and interfaces chemistry, electrochemistry, biotechnologies, organic electronic devices. It involves the molecular control of reactions at interfaces, the organization of molecular nanodomains and the implementation of various physico-chemical characterization methods. A central axis dedicated to biosensors: detailed understanding of the physical and chemical phenomena associated with electron transfer and transport processes; development of innovative and efficient biosensing technologies.
