- Abstract: The rapid nucleic acid extraction is essential, particularly the communicable diseases pandemic. In this work, aluminum modified Fe3 O4 (Fe3 O4 @Al 3+ ) particles were successfully synthesized by solvthermal method, epoxidation, covalent binding of iminodiacetic acid and Al 3+ ions coordination for DNA extraction. Fe3 O4 @Al 3+ particles could greatly improve the efficiency of DNA extraction and the extraction could be totally completed within 15 minutes at the optimum condition. The simple and rapid method is mainly based on the Fe3 O4 @Al 3+ particles, which have large specific surface area, superparamagnetism, and Al 3+ ions affinity to DNA. Additionally, several characterizations were carried out to further investigate the features of Fe3 O4 @Al 3+ particles. According to SEM image, the average dimension of monodispersed Fe3 O4 @Al 3+ spheres was around 200 nm. XPS results showed the existence of Al 3+ on the surface of Fe3 O4 particles, which further demonstrated the success of metal chelation in this material synthesis. The XRD patterns indicated that the Fe3 O4 @Al 3+ particles were the inverse spinel structure as the bare Fe3 O4 particles. Good magnetism of Fe3 O4 @Al 3+ particles determined by VSM indicated that this material could be easily separated from the reaction system. To summarize, Fe3 O4 @Al 3+ particles is expected to play an important role in future DNA extraction due to remarkable performance.
