The one or more multi-dentate ligands are bound to the surface of the magnetic nanoparticle through one or more dithiocarbamate groups. The one or more multi-dentate ligands may be a compound of Formula II:RNCH[CHNR'CH][CHN(CS)CH][CHNHCH]CHNR″  (II)where each R, R′, and R″ are independently H, a branched ethyleneimine unit, an unsubstituted or substituted alkyl, an unsubstituted or substituted alkenyl, or an unsubstituted or substituted aryl; and n is an integer from 1 to about 50.
