Beschreibung
Zusammenfassung:	A composite having a small particle diameter and composed of a water-soluble carboxypolysaccharide and a magnetic iron oxide having a core diameter ranging from about 2 to about 7 nm, wherein the overall diameter ranges from about 10 to about 50 nm, the ratio of the overall diameter to the core diameter is about 15 or less, and the T2 relaxation capacity ranges from about 10 to about 150 (mM.sec) . The composite is reduced in toxicity and side effects and is useful as iron preparation, X-ray contrast medium, MRI contrast medium, reagent for blood stream measurement, drug carrier, and so forth in the fields of medicine, biology and engineering.
