A biocompatible process to prepare hyaluronan-based material able to self-assemble into stable nano-particles

New self-assembled nano-particles were developed by chemical conjugation of natural fatty acids to the backbone of hyaluronan (HA). The chemical structure and the self-association behavior of them were studied by FT-IR, NMR, fluorescence and dynamic light scattering. The HA derivatives form stable spherical shape aggregates, as assessed by transmission electron microscopy. This journal is
