✦ Synopsis

Abstract

Colloidal photonic crystals were prepared from monodisperse core–shell particles. The shell is hereby formed from a functional monomer, such as glycidylmethacrylate or different reactive ester monomers, which can perform chemical reactions and the core from a standard monomer, which yields highly monodisperse colloids. It was possible to crystallize the core–shell particles into artificial opals with excellent optical properties. Reactions on the functional surface of the colloids were carried out, which lead to a dramatic rise in the mechanical stability or to a functionalization of His‐tagged silicatein, which acts as nanoreactor to synthesize and immobilize gold nanoparticles from auric acid onto the core–shell colloids.

## Abstract We have found that a soft, hydrophilic shell is necessary in the formation of three‐dimensional colloidal crystals by polymeric microspheres prepared by surfactant‐free emulsion copolymerization. The core‐shell microspheres contain a hard, hydrophobic polystyrene core and a soft, hydrop
