TFFFC (Toulouse FFF Center) is a platform dedicated exclusively to field-flow fractionation (FFF) techniques used to characterize macromolecules and nanoparticles. It contains four asymmetrical-flow FFF (AF4) systems—including 2D systems—with an electrical AF4 (EAF4) module, a sedimental FFF system, a thermal FFF system, and a capillary electrophoresis system. The platform supports industries and public labs working on agri-food, cosmetic, pharmaceutical, chemistry, and environmental sciences.

In this webinar, we discuss three recent case studies employing FFF:

  • Characterization of polyoxazoline nano-vectors for photodynamic therapy
  • A study of the structural conformation of enzymatic cross-linked caseins particles in neutral and acidic conditions
  • Analysis of ultra-high molar mass polyacrylamides used for oil extraction
