From Metal Binding to Nanoparticle Formation: Monitoring Biomimetic Iron Oxide Synthesis within Protein Cages using Mass Spectrometry

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: rel...

Zusammenfassung: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).
