Based on the basic principles of biomineralization, a novel aragonite (CaCo_3) with specific morphology was synthesized under the control of-cyclodextrin by the biomimetic method. In our experiments, the β-cyclodextrin were used as the organic matrix. The obtained composite CaCO_3 with small amount of β-cyclodextrin were characterized by X-ray powder diffraction (XRD) analysis and scanning electronic microscopy (SEM). Furthermore, according to the results of Fourier transform infrared spectroscopy (FT-IR) and measurement of conductance ratios, the possible mechanism of the interaction between β-cyclodextrin and CaCO_3 during the CaCO_3 formation process was discussed.
