Abstract

In order to detect DNA, we employed nano magnetite powders of Fe₃O₄. In XRD results, the nanoparticle was synthesized mainly in magnetite phase and also maghemite (r-Fe₂O₃) phase was trivial portion. The surface morphology of the powders observed that the particle size was about 40 nm and did not change as varying annealing temperature. In agarose gel electrophoresis analysis, after bonding DNA, Fe₂O₃ and Fe₃O₄ nanopaticles showed the fixed state in the range of lane 2-4. But the mixed particles were very weak reaction when compared with Fe₃O₄. Additionally, Fe₃O₄ presented the reaction of DNA in lane 5~7. From these results, we confirmed a chance of DNA detection by using the nanoparticle.
