Shape-selective coprecipitation synthesis of ca. 30 nm uniform magnetite nanocrystals (see figure) is performed with an iron-binding biomineralization protein, Mms6. The effect of Mms6 mineralization protein in magnetite synthesis is compared to that of several other proteins and is found to provide a selective bioinspired route for the synthesis of superparamagnetic nanocrystals.
