Constrained Synthesis and Organization of Catalytically Active Metal Nanoparticles by Self‐Assembled Protein Templates

Novel geometrical architectures of hybrid nanoparticle–protein complexes are generated by chemically synthesizing monodisperse metal nanoparticles in situ in the presence of a stable, stress‐related protein. The catalytic activity of the protein–particle hybrids is examined for the reduction of 4‐nitrophenol, providing future biofunctional nanoparticle labels for catalytic signal amplification in optical assays.
