Claim Text:
1. A method of producing a nanoparticle suspension, the method comprising: (i) converting one or more precursor substances in an emulsion to nanoparticles in a disperse polar phase, wherein the disperse polar phase comprises the one or more precursor substances in a continuous nonpolar phase in the presence of an emulsifier stabilizing the emulsion; (ii) breaking the emulsion and phase separating the disperse polar phase to obtain at least one nanoparticle suspension as at least one phase, such that the breaking of the emulsion is effected by splitting the emulsifier; (iii) separating off the nanoparticle suspension; and (iv) optionally isolating nanoparticles from the nanoparticle suspension, wherein: the emulsifier is at least one compound of formula (I): X is O, NH, or NR Y is C(O), NH, or NR R is a saturated or a mono- or polyunsaturated, linear or branched hydrocarbon radical having 6 to 30 carbon atoms; R R R n is 0 or 1.
