9-3-single strand helicoidal nanofibers of photo-active polyoxazolines

The polyoxazolines is an attractive polymers family characterized by a pseudo-peptidic structure, own bio and
hemocompatibility, low toxicity and furtivity towards immune systems-basic properties for biomedical applications. They
offer an additional attraction with the ability to self-assembly under various morphologies including spherical nanoparticles,
nanowires using hydrogen bonds, dipolar interactions, etc. In this study, we focused on poly (2-methyl-2-oxazoline) decorated
by coumarin units, able to photo-activity and able to pi-stacking and further original self-assemblies as already shown with
peptides. In a previous work, we demonstrated the UV-activity and the self-organization of amphiphilic di-block and tri-
block co-polyoxazolines in water. Herein, well-defined single strand helicoidal fibers were elaborated using amphiphilic
graft copolymers. These polymeric filo micelles grow according to Crystallization-Driven Self-Assembly (CDSA) between
polyoxazoline repetitive units and the coumarin ones. In other experimental conditions, the UV-activity of spherical
nanoparticles of the same copolymers were also examined particularly the photo-cross-linking of the nanoparticle core.
