Electrospun Cactus Mucilage/Poly(vinyl alcohol) Nanofibers as a Novel Wall Material for Dill Seed Essential Oil (Anethum graveolens L.) Encapsulation: Release and Antibacterial Activities

This study, a collaboration work with University of Sfax and Grenoble INP, aimed to create long-lasting molecular carriers by producing electrospun nanofibers from cactus mucilage and poly(vinyl alcohol) loaded with dill seed (Anethum graveolens L.) essential oil (DSEO). The electrospun nanofibers enabled controlled long-term release of DESO. The DSEO-containing nanofibers demonstrated bacteriostatic and bactericidal activities […]

Enantioselective membranes prepared by electrospinning of cellulose tris(3,5-dimethylphenyl carbamate) having various degrees of polymerization: effect of the DP on the morphology

Recently, we reported a proof of concept of enantioselective membrane filtration using a nonwoven membrane prepared by electrospinning of cellulose tris(3,5-dimethylphenyl carbamate) (CDMPC) synthesized from microcrystalline cellulose. In the present work, CDMPCs having higher degrees of polymerization were synthesized from cellulose fibers derived from hardwoods by a collaboration with Centre Technique du Papier granted by […]

Sugars, a new weapon against infections!

Glycobiology, the study of the biological functions of carbohydrates, is a field of research in its own right, which could one day lead to new treatments against infections. Anne Imberty, CNRS Research Director at Cermav, was interviewed in the CNRS journal on this topic, with Yann Guérardel as co-guest. The article is available here: https://lejournal.cnrs.fr/articles/les-sucres-nouvelle-arme-contre-les-infections […]

Deciphering GAGs: a new way of sequencing polysaccharides

Les variations du courant mesurées à travers une membrane lors du passage d’une biomolécule à travers le nanopore protéique s’avère être une méthode puissante de séquençage de polysaccharides de structure complexe. Elle permet d’en déterminer la taille, la nature et l’enchaînement des briques constitutives et leur degré de fonctionnalisation. © Régis Daniel

In this publication involving Bernard Priem, Lecturer at the University of Grenoble Alpes, the authors propose an effective and robust approach based on passage through protein nanopores, to decipher the structure of complex bioactive polysaccharides, GAGs. Click on the title for more information.
