| titleOfInvention | Method for preparing gold-coated magnetic composite nanoparticles |
| abstract | The invention discloses a method for preparing gold-coated magnetic composite nanoparticles, and belongs to the technical field of multifunctional composite nanoparticles. The method comprises the following steps of: dissolving hydrophobic magnetic nanoparticles in cyclohexane to serve as an oil phase; dissolving a gold-philic surfactant in de-ionized water to serve as a water phase; ultrasonically mixing; then protecting a volatile solvent with nitrogen to obtain magnetic aggregate aqueous solution of which the surface is modified by the gold-philic surfactant; secondly, adding chloroauric acid, a reducing agent and a stabilizing agent into the magnetic aggregate aqueous solution; and reacting to obtain gold shell-covered magnetic aggregate composite nanoparticles. In the method, a gold shell is directly grown on the surface of a magnetic aggregate; and the nanoparticles have the advantages of continuous adjustable gold shell, adjustable adsorption spectrum, adjustable magnetic content, simple preparation method and the like. |
