Magnetic nanoparticle assemblies on denatured DNA show unusual magnetic relaxivity and potential applications for MRI.
Denatured (substantially single-stranded) herring sperm DNA acts as a template for the preparation of magnetic nanowires, forming stable aqueous suspensions, which exhibit unprecedentedly high relaxivity at low field, suggesting that the material may be a potentially useful reagent for MRI.
