Bulletin SFN-2FDN (January 2023)

Actualités

La SFN et la 2FDN vous souhaite une très bonne année à toutes et à tous, riche en échanges et en résultats scientifiques !

Nous attendons avec impatience le redémarrage de l’ILL, le démarrage de SANS-LLB@PSI et tous les évènements à venir pour cette année.
Les dates des FANs (Formation à la Neutronique) seront très prochainement annoncées et auront lieu en fin du prochain cycle de l’ILL.

Désormais, le bulletin sortira en début de mois avec le nom du mois en cours. Celui-ci est donc celui de janvier 2023.

Hybrid systems combining liposomes and entangled hyaluronic acid chains: influence of liposome surface and drug encapsulation on the microstructure

Mixtures of hyaluronic acid (HA) and liposomes are efficient drug delivery systems for applications in otology and ophthalmology, yet little is known about their microstructure. In this study, we used SANS to demonstrate that liposomes keep their integrity in a matrix of HA chains, whether they are anionic, cationic, or decorated by poly(ethylene glycol) chains, and whether they contain or not a corticoid. We also demonstrate that their aggregation state is driven by how their surface interacts with the HA chains.
