| 摘要 |
<p>The invention concerns a method for making very fine particles containing at least an active principle inserted in a host molecule and a device for implementing said method. The method is characterised in that it consists in forming a solution of the active principle in a first liquid solvent and of a product formed by the host molecules in a second liquid solvent, then in contacting the resulting solutions with a supercritical pressure fluid, so as to precipitate the host molecules which are dissolved therein.</p> |
