Séminaire N. Baccile "Microbial glycolipid biosurfactants: from self-assembly to hydrogel formation"

Niki Baccile (LCMCP), Université Pierre et Marie Curie

Jeudi 11 janvier 2018 - 14h00 - Amphi à définir

"Microbial glycolipid biosurfactants : from self-assembly to hydrogel formation"

The use of hydrogels is expanding in many fields, from thickeners, to drug encapsulation, wound healing, etc... Microbial glycolipid biosurfactants, the gelling conditions of which in water have never been described, have a great potential in this field. This class of compounds, obtained from renewable resources via a fermentation process from yeasts or bacteria, is biocompatible, non-cytotoxic and it exhibits astonishing stimuli-responsive self-assembly properties in water.1,2 The presentation will then focus on the self-assembly properties of microbial glycolipids, studied by SAXS and cryo-TEM, and it will show some ongoing work concerning their hydrogel-forming properties, mainly probed by time, temperature and pH-resolved rheology experiments (Figure 1).
