| 摘要 |
The invention relates to microparticles having a uniform spherical shape and showing a very narrow dimensional distribution. These microparticles are fully or partly composed of a linear water insoluble polysaccharide, preferably 1,4.alpha.-D-polyglucan, and they can contain other, preferably biodegradable, polymers and/or active ingredients. They can, inter alia, be used for the controlled release of active ingredients. The are produced by dissolving the 1,4-.alpha.-D-polyglucan or said polysaccharide in a solvent, mixing the solution with a precipitating agent, cooling the mixture and separating the formed particles.
