(Angew. Chem. Int. Ed. 12/2006)

Form development......during growth of fluorapatite–gelatine nanocomposites is effected by pre-structuring of gelatine matrices by ion impregnation. The cover picture shows the hierarchical fractal aggregate (background), structural details of a fanlike aggregate, and a simulation of the “stiffening” effect on a protein molecule of Ca2+ ion incorporation. This effect is discussed by R. Kniep and co-workers in their Communication on page 1905 ff. A second paper on page 1911 ff. deals with the effect of intrinsic electric dipole fields on the form development of the nanocomposite materials.
