Monodispersed Fe3O4 magnetite nanoparticles were successfully synthesized via a simple solvothermal method, in which Fe(NO3)3•9H2O was used as the starting materials, KOH as the mineralizer, and ethylene glycol (en) as the solvent. X-ray diffraction (XRD) and selected area electron diffraction (SAED) were employed to characterize the phase composition, transmission electron microscope (TEM) to observe the morphology and the particle size, and physical property measurement system (PPMS) to investigate the magnetic property of the synthesized powders, respectively. The synthesized Fe3O4 magnetite nanoparticles are of 50-100nm in size, and of notable ferromagnetic property. The saturation magnetization, remanent magnetization, and coercive field are 68.8emu•g-1, 12.9emu•g-1, 138.5Oe, respectively. Based on the experimental resuts, the formation mechanism and the well monodispersed reason of the solvothersized Fe3O4 nanoparticles are discussed.

Copper sulfide nanoparticles have been employed as artificial mimics for peroxidase-like activity. In the present study, copper sulfide nanoparticles with four different morphologies have been synthesized by thermal decomposition of cyclo-tri-μ-thioacetamide-tris(chlorocopper(I)) complex ([Cu3TAA3Cl3]) at 200 °C in different solvents such as diphenyl ether, ethylene glycol, 1-octadecene and also without any solvent. Hierarchical copper sulfide nanostructures are formed when the complex is decomposed in the absence of solvent, in diphenyl ether, and 1-octadecene while in the case of ethylene glycol, randomly agglomerated nanoparticles are formed. The precursor complex ([Cu3TAA3Cl3]) as well as copper sulfide nanoparticles were characterized using an array of techniques and after characterization, the peroxidase-like activity of copper sulfide nanoparticles was investigated.Morphologically different copper sulfide nanoparticles possess different exposed facets and due to this, the peroxidase-like activity was different among different morphologies.
