Patent number: 7344895Abstract: 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.Type: GrantFiled: December 6, 2003Date of Patent: March 18, 2008Assignee: Bayer Technology Services GmbHInventors: Burkhard Köhler, Kerstin Bohmann, Werner Hoheisel, Markus Haase, Stefan Haubold, Christiane Meyer, Thorsten Heidelberg

Patent number: 7288239Abstract: The invention relates to synthesis of nanoparticles, in particular to methods for producing nanoparticles with networks consisting of Z sulphate (Z=magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba) or the binary mixtures thereof). The inventive method consists in synthesising the nanoparticles by crystal growth from an ion Z source and a sulphate ion source in a liquid phase mixture. The invention produces Z sulphate nanoparticles having a small diameter and uniformly dispersible in water or other solvents in a simple way. Co-ordinating solvents like glycerine, glycol ethylene and other polyethylene glycols, polyalcohols or dimethylsulphoxide (DMSO) are used for the synthesis mixture.Type: GrantFiled: November 19, 2003Date of Patent: October 30, 2007Assignee: Nanosolutions GmbHInventors: Fernando Ibarra, Christiane Meyer, Stephan Haubold, Thorsten Heidelberg
