Trace elements, Green Techniques,

Environmental water pollution and environmental impacts

- Design of sensor molecules and optical sensors in the determination of metals.
- Ecotoxicological effects caused by the presence of metallic nanomaterials in aquatic systems and possible biomarkers sensitive to these emerging pollutants.
- Study of the potential of plant and food residues as metal biosorbents.
- Assessment of metal contamination in aquatic ecosystems: speciation, bioaccumulation, ecotoxicological effects and bioindicators of metallic contamination.
- Innovation in preconcentration, separation and trace element analysis methodologies

Application of chemometric techniques to electroanalytical and spectroscopic data.
Electrochemical and structural characterization of nanomaterials and ceramic and composite materials.
Contribution of different analytical techniques to the resolution of real problems.
Quality control and food security.
Development of new electrode (nano)materials.

The aim of the scientific group is the development of multifunctional potentiometric sensors in solid state with membranes with the addition of nano particles. A secondary objective is to develop simple potentiometric sensors for the determination of chemical species of interest that would have improved properties. Improved sensor performance will be based on simpler preparation of samples for analysis (does not matter discoloration and turbidity of the sample), improved chemical, physical and electrical properties.

The ‘Laboratoire de Chimie, Electrochimie Moléculaires et Chimie Analytique, UMR CNRS 6521 – UBO, CEMCA’ (‘Molecular Chemistry, Electrochemistry and Analytical Chemistry’ Laboratory) is a joint, CNRS and University of Brest, research laboratory. It is located in Brest at the Faculty of Science and Technology. This laboratory was created in the early eighties (1981) by the fusion into a single research unit of four teams having expertises in organic, inorganic, physical and analytical chemistry. That is the sole research laboratory in chemistry of the University of Brest.
