Alles unter Kontrolle: In Gegenwart des künstlichen doppelt-hydrophilen Blockcopolymers Polyethylenglycol-b-poly(L-glutaminsäure) kristallisieren aus einer Mischung von N,N-Dimethylformamid und Wasser hoch monodisperse Vaterit-Mikrokügelchen (siehe Bild). Änderungen des Lösungsmittelverhältnisses beeinflussen die Morphologie der CaCO3-Kristalle.
