A novel nanoparticle hybrid is attained by the covalent attachment of iron oxide ( γ ‐Fe 2 O 3 ) nanoclusters onto the surface of a mutagenized cow pea mosaic virus (CPMV‐T184C). Using a stepwise substrate‐based integration, monodisperse CPMV‐IO hybrids are anchored on a gold substrate. The physical and magnetic properties of individual CPMV‐IO hybrids are qualitatively investigated by atomic/magnetic force microscopy (AFM/ MFM). During MFM characterization a ‘boundary‐effect’ is observed at the CPMV/IO interface.
