•   We have investigated the effective synthesis of Pyrococcus furious virus like particle (PfV) and the integration of Ni2+ ions with PfV. Application of Isopropyl-β-D-1-thiogalactopyranoside (IPTG) during incubation of P. furious causes the marked improvement of yield of P. furious. Using the synthesized P. furious, the spherical structure of PfV is successfully obtained. Concerning magnetism, the native PfV shows the diamagnetic properties. On the contrary, after the integration with Ni2+ ions, the paramagnetic behavior appears, namely the non-saturated M-H curve with zero remanence and coercivity, and Curie law like M-T curve. The obvious changes in the magnetic properties indicate that the Ni2+ ions are successfully integrated with PfVs.
