CA 2070095

Novel smooth surface microspheres having a diameter of between 1 µm to 100 µm are provided herein. Such microspheres comprise a particular biologically-active molecule, namely, a high molecular weight molecule of a proteic nature or of a glycosphingolipid nature and an ester of hyaluronic acid or mixtures of the esters of hyaluronic acids. In these smooth surface microspheres, the biologically- active molecule is adhered to the ester of hyaluronic acid. Such smooth surface microspheres have utility for the controlled release of the biologically-active molecule.
