Microemulsion-Mediated Self-Assembly and Silicification of Mesostructured Ferritin Nanocrystals

Protein crystals turned to stone: Protein‐mediated aggregation of microemulsion water droplets is used to prepare discrete ferritin nanocrystals with periodically arranged close packed structures. Addition of tetramethoxysilane (TMOS) to the microemulsion produces silica‐ferritin hybrid nanoparticle...

Description
Summary:Protein crystals turned to stone: Protein‐mediated aggregation of microemulsion water droplets is used to prepare discrete ferritin nanocrystals with periodically arranged close packed structures. Addition of tetramethoxysilane (TMOS) to the microemulsion produces silica‐ferritin hybrid nanoparticles with well‐ordered mesostructured interiors (see scheme).
