Graphical Abstract
Small world: Metallic nanomagnets (MNMs) dispersed in spherical colloids can be prepared by the aerosol evaporation of an aqueous sol containing mineralized ferritin and a colloidal matrix precursor (see picture). Essential to the success of the method is the template effect provided by ferritin.

- 16We did not try to eliminate the inorganic phosphate, because of the small amount of phosphate with respect to iron in native horse spleen ferritin (usually about 5 mol % of the Fe content, Ref. [11a]) and the fact that its presence could even help to stabilize the metallic phase against corrosion (phosphates are routinely used in metallurgy as anticorrosive agents). When the reduction, elimination, or even addition of inorganic phosphate is needed for other systems, protocols can be found in the literature (see for example reference [11b]).
- 17Apart from α-Fe, we expect the formation of a low-crystallinity Fe2SiO4 shell (not observable by XRD) surrounding the α-Fe MNMs, as happens in Fe/silica systems obtained in a similar way (see references [7c] and [15d]). This protective layer imparts stability against corrosion of the metallic component.

- 19The Fe and Co atoms form a metallic alloy throughout the range of compositions and we expect, at the end of thermal treatment, the diffusion of Co atoms within the Fe metallic core. In fact, the formation of Fe1−xCox metallic alloys is reported in the literature by using methods such as ball milling (see for example M. Sorescu, A. Grabias, Intermetallics 2002, 10, 317 and E. C. Passamani, C. Larica, V. P. Nascimento, J. Mater. Sci. 2002, 37, 809).
