  • 4-Aminothiophenol (4-ATP) functionalized silver nanoparticles and magnetic Fe3O4 nanoparticles were combined in a bi-functional nanocolloids which were covered by an approximately 5nm SiO2 layer by inverse emulsion method in order to apply to biomedicine. High saturated magnetization Ms indicated that the colloids are easy to be controlled by external magnetic field, while the characteristic Surface Enhanced Raman peak positions of 4-ATP absorbed on the metal particles were occurred without any alterations, which significantly predicted attractive applicability of the colloids for biomedical labeling.

  • ZnS:Mn- Fe3O4 bifunctional nanoparticles were synthesized by inverse microemulsion method for biomedicine applications. The bifunctional nanoparticles were combined from prepared ZnS:Mn and Fe3O4 nanoparticles in a SiO2 cover matrix. Results show that bifunctional nanoparticles, apart from exhibiting magnetism, have photoluminescence properties, which support the applications targeting biomedicine fluorescent diagnostics as well as magnetic cell sorting or drug delivery.

  • In this paper, Fe3O4-ZnO heterostructure multifunctional nanoparticles (NPs) were successfully prepared in aqueous solution by ultrasound assisted thermolysis. First, iron oxide (Fe3O4) magnetic NPs were prepared by co-precipitation method. The Fe3O4 NPs were modified by 3-aminopropyltriethoxysilane (APTES) to have free amine (-NH2) groups on their surface, then, Zn2+ ions were added and stirred to adsorb onto the surface of Fe3O4-NH2 NPs in alkaline solution at a pH of 11. This solution was decomposed through thermolysis in ultrasound bath. The results of measurements show that photoluminescence of Fe3O4-ZnO heterostructure multifunctional NPs was enhanced in visible light at 565 nm ...
