The invention relates to a method for the production of nanoparticles comprising a conjugated polymer. The method comprises (i) providing a reaction mixture with a monomer, a photosensitising agent and a solvent, and (ii) exposing the reaction mixture to photo-irradiation to form nanoparticles of a conjugated polymer wherein the photosensitising agent is immiscible with the solvent.
