Abstract (en)
[origin: WO03080034A2] The invention relates to a method for producing microparticles and/or nanoparticles of a substance, wherein particles are formed from a molecularly distributed substance which is simultaneously stabilised in a suspension. The substance is dissolved in a solvent system and subsequently a non-solvent for said substance is added whereby said non-solvent can be mixed with the solvent system for said substance. One or several crystal growth inhibitors are added and a rapid merging of solvents and non-solvents takes place. The substance is precipitated by forming a dispersion of particles whose size lies within the micrometer or nanometer range.
