Abstract: A process for synthesizing nanoparticles, in particular metal salt nanoparticles. To the synthesis mixture is added a modifying reagent which binds, by means of a first functional group, to the nanoparticle surface and which carries a second functional group for binding to molecules which are specifically selected in dependence on the subsequent use of the nanoparticles. This dispenses with a postsynthetic, separate, application-specific modification step. A new substance class, the pentaalkyl iminobis(methylenephosphono)carboxylates, are particularly suitable for this purpose.
