In this work‚ the Fe3O4 NPs were synthesized by a co-precipitation method. The prepared Fe3O4 particles were dispersed well in water and stay stable for several days. FT-IR spectra of Fe3O4‚ mercaptosuccinic acid and mercaptosuccinic acid functionalized Fe3O4 are shown in Figure 1(a-c)‚ respectively. In Figure 1a‚ the sharp band at about 585 cm-1 corresponds to the characteristic Fe–O vibration peak and the bands at around 3420 cm-1 are due to the stretching vibrations of the hydroxyls (–OH) on the
