The invention provides a biomimetic process for preparation of nanosized iron oxide particles used for the enhancement of magnetic resonance imaging contrast. The process involves a weak complexion (via dative bond formation) of ferrous/ferric ions (acceptor atom) with the active functional groups (donor atom) of polymer. The nanosized iron oxide, is biodegradable, nontoxic and has size in the range of 4-20 nanometer.
