Nanostrutture inorganiche funzionali via miniemulsione: sintesi, caratterizzazione e funzionalizzazione

In this work a miniemulsion based approach was used for the synthesis of pure and doped copper sulphide nanostructures. Different sources of sulphide, like sodium sulphide, thioacetamide, thioacetic acid, thiourea and ammonium thioglycolate, were investigated to obtain pure and crystalline products. Complementary techniques (FT-IR, TEM, SEM, XRD, XPS and XAS) were used for a thorough characterization of the nanoproducts. For future bioimaging application, zinc oxide nanoparticles, synthesized via miniemulsion, were coated by a biocompatible polymeric ligand to enable them to be re-dispersed in acqueous media. The ligand chosen for this aim is a polymethyloxazoline (PMOXA) terminated with a nitrodopamine because this one is a good anchor for oxide surfaces. Functionalized nanoparticles were characterized by FT-IR and AFM and successfully re-despersed in water to form stable suspensions.
