The present invention relates to a method for preparing bioabsorbable microparticles to which proteinaceous substances are attached, characterized in that it comprises the steps of: (i) preparing said microparticles from at least one bioresorbable polymer without stabilizing agent and without surfactant, and (ii) binding of said protein substances to the microparticles obtained in step (i) without surfactant. It also relates to the bioresorbable microparticles thus obtained and their use in diagnosis and therapy. |
