PROJECT SUMMARY

             In this project we are focused on synthesis and characterization of various core-shell or multi-shell nanoparticles based on Fe, Pt, conjugate polymers and silica or titania components.

 

           General objective: Synthesis, characterization and applications of various types of Fe and Pt based nanoparticles with adjustable properties involving magnetic, dispersive and functional characteristics.

 

 Specific objectives:

1. Synthesis, structural and compositional characterization of multi-shell Fe@FePt_L10@Pt nanoparticles;

2. Magnetic characterizations of Fe@FePt_L10@Pt nanoparticles; adjustment of the coercive magnetic field based on synthesis – properties relationship;

3. Synthesis, structural and compositional characterization of multi-shell FePt_L10@PPy and/or FePt_L10@P3HT hybrid nanoparticles;

4. Magnetic characterizations and saturation magnetization adjustment by use of a suitable choice of polymer shells;

5. Synthesis, structural and compositional characterization of multi-shell FePt_L10@SiO₂ and/or FePt_L10@TiO₂ core-shell composite nanoparticles;

6. Magnetic characterization dispersion adjustment of FePt_L10@SiO₂ and/or FePt_L10@TiO₂ nanoparticles;

7. Hyperthermia tests with various Fe@FePt_L10@Pt nanoparticles, having different FePt_L10 intermediate shells, dispersed in water based solutions and gels;

8. Functionalization of Fe@FePt_L10@Pt, FePt_L10@PPy (P3HT) and FePt_L10@SiO₂ (TiO₂) nanopatricles in view of magnetically molecular separation and uptake tests from water based solutions.
