The synthesis and characterization of carbon-coated ferromagnetic nanoparticles that organize into 1-D assembliesof micrometer-sized ferromagnetic chains is described. A controlled aromatization and carbonization of glucose underhydrothermal reaction conditions enabled the preparation of carbonaceous surfactants that were used as shells for thecoating of ferromagnetic Fe3O4 nanospheres with a uniform size distribution. Under controlled experimentalconditions, it was, for the first time, demonstrated that glucose could be employed as the carbon source in thepreparation of continuous 1-D carbon nanoparticle chains with magnetic nanosphere inclusions. The functional groupson the carbon surface will facilitate the linkage of functional groups or catalytic species to the surface in future
application. The salient feature of the reported method was the assembly of magnetic nanospheres under hydrothermalreaction conditions in the absence of external fields
