Schematic illustration of M13-bacteriophage-mediated targeting of magnetic nanoparticles for MRI. The M13 bacteriophages were modified with SPARC-binding peptides of the p3 motif and subsequently with p8 proteins with a triglutamate motif for multivalent assembly of iron oxide nanoparticles (black circles).
