摘要：

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.
