An Ag@Fe_3O_4@C-Au microspheres has been developed which including the synthesis of Ag@Fe_3O_4 by one-step via a versatile solvothermal reaction, an interlayer of carbon shell coating around the Ag@Fe_3O_4 with glucose as carbon source, the surfuce of Ag@Fe_3O_4@C modified by PEI via amidation reaction, and the coating Au nanoparticles on the surface of Ag@Fe_3O_4@C. The enhancement effect in the Raman active was investigated by using 4-mercaptobenzoic acid(4 MBA) molecules as a probe molecule. In addition,...
