Laboratory of nanometric structures (NIMBE/LEDNA)

Laboratory of nanometric structures (NIMBE/LEDNA)

The studies of the LEDNA laboratory are focused on five main projects:

  • Synthesis of various nanoparticles by laser pyrolysis (Si, Si@C, oxides, carbides,…),
  • Synthesis of carbon nanostructures by CCVD (vertically aligned carbon nanotubes, graphene),
  • Synthesis of gold nanoparticles for plasmonics
  • Nanostructured electrocatalysts for oxygen reduction (fuel cells),
  • Chemical sensors based on materials containing functionalized and size-controlled nanopores.

Finally, to address social issues on the risks associated with engineered nano-objects, the group has invested heavily in the study of the toxicological effects of nano-objects.

    Advanced Electrochemical Microscopy (SECM)

    Electrochemical microscopy (SECM, for Scanning ElectroChemical Microscopy) is an electrochemical technique developed in the late 90s. It involves bringing a micrometer-sized electrode close to the surface to be studied. Depending on the nature of the electrolyte in which the experiment is carried out, and the potential conditions imposed on the electrode and substrate, we can…

    Ionic Chromatography

    Ion chromatography (or ion-exchange chromatography) is a form of chromatography that separates ions and ionizable polar molecules based on their affinity to the ion exchanger. It works on almost any kind of charged molecule—including small inorganic anions, large proteins, small nucleotides, and amino acids. However, ion chromatography must be done in conditions that are one…
