Abstract (en)

[origin: WO2009027433A2] The invention relates to a method for producing coated nanoparticles which comprise a core holding at least one first substance and at least one envelope from at least one additional substance that at least partially surrounds the core, in a fluid system. The invention also relates to nanoparticles obtainable by said method, to nanoparticles comprising a non-porous core that holds at least one first substance, and at least one envelope from at least one additional substance that at least partially surrounds the core, the nanoparticles having a narrow particle-size distribution. The invention finally relates to the use of the nanoparticles in photocatalysis and to a device for carrying out the method.
