| Abstract: | 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; nFe: number of Fe atoms).  |
