We reported the synthesis and characterization of Fe 3 O 4 magnetic nanoparticles modified β-cyclodextrin polymer (MNP@βCD-TDI) for the adsorption of deoxyribonucleic acid (DNA). The synthesized MNP@βCD-TDI was characterized by Fourier Transform Infra-Red spectroscopy and Vibrating Sample Magnetometer. Experiments were performed in a batch mode and parameters that affected the DNA adsorption were investigated. An evaluation of the adsorption behavior revealed that Freundlich model and pseudo-second-order fit the equilibrium data. The adsorption efficiency of DNA was found to be at 70 ± 5 % after being recycled three times. This study could be used as a general platform for future work on DNA adsorption and enrichment. © 2018, © 2018 Taylor & Francis.
