Beschreibung
Zusammenfassung:	A biodegradable hyaluronic acid derivative comprising a modified hyaluronic acid repeating unit represented by the formula (HA)-[O(C=O)NH-M]p, wherein HA is a unit including N-acetyl-D-glucosamine and D-glucuronic acid, M is a modifying moiety containing a C2-16 hydrocarbyl group or a prepolymer, and p is an integer of 1 to 4. The biodegradable hyaluronic acid derivative when dissolved in a hydrophilic medium can form micelles and can be used to entrap a pharmaceutically active or bioactive molecule.
