| abstract |
The invention relates to a method for producing nanoparticles with diameters of between 10 and 300 nm, comprising the following steps: (a) dissolving organic active agents in a solvent in supercritical or near-critical conditions; (b) expanding the fluid mixture into a gas or a liquid using a nozzle; and (c) evaporating the solvent at the same time. The method is characterised in that emulsifiers and/or protective colloids are also used. |
