Sweet nanomagnets: Suspensions of glycopeptide grafted magnetic nanoparticles can be produced by N-carboxyanhydride ring-opening polymerization with subsequent click glycosylation. The resulting materials have a high sugar density, optimal dispersion and T1-weighted MRI properties, and bio-recognition ability. The approach can be used to attach any type or combination of functional groups, the density of which is not limited by particle surface area.
