A simple and convenient method to make a novel material of DNA-coated magnetic-fluorescent composite particles was presented in this article. Hydrothermal synthesis was used for obtaining Fe3O4 magnetic nanoparticles. After modified by oleic acid, the nanoparticles were coated by the macromolecular shell, which came form the polymerization of ethyleneglycol dimethacrylate and methacrylic acid. With the help of ethylenediamine as linker molecules and the condensation effect of ethyl (dimethylaminopropyl) – carbodiimide and N-Hydroxysuccinimide (EDC/NHS) reaction system, salmon DNA were linked to the surface of the shell. After labeling a fluorescent dye Syber Green Ⅰ®, the magnetic-fluorescent composite particles were produced.

Fe3o4 Magnetic Nanoparticles

A method of the hydrothermal synthesis of Fe3+-doped titanate nanotubes (TNT) is reported in which the ultra-small Fe3O4 nanoparticles are used as the sources of Fe3+ ions. The magnetic nanoparticles with a diameter of about 2 nm are added during the washing stage of the hydrothermal procedure. During washing, they gradually degrade and at the same time, the titanate product is transformed into nanotubes. The obtained nanotubes were characterized by structural and magnetic measurements. It was found that, depending on the value of the external magnetic field, they may show the property of room temperature ferromagnetism, paramagnetism or they may be diamagnetic. It was also shown that the modified TNTs have greater photocatalytic activity compared to unmodified TNTs.
