Mass measurements of metal‐mineralized protein cages allowed quantitative examination of the effects of metal‐ion concentration on the final nanoparticle size. Modeling using a kinetic master equation suggests that particle growth involves both a binding phase and a growth phase (see picture; I : relative abundance; LiDps: a DNA binding protein; n Fe: number of Fe atoms).
