Subdomain metal or metal oxide particles covalently coupled to chemically reactive organic moieties and subsequently reacted together to form biodegradable magnetic microclusters are disclosed. The magnetic microcluster can be used as contrast agents in NMR imaging for the production of images suitable for use in diagnosis, for in vivo delivery and targeting of drugs, as in vivo, biodegradable agents for the sequestering of free metal ions in the treatment of metal driven disease.
