The magnetic iron oxide oxide nanoparticles [Fe-nanoparticles] were prepared as described [64-66]. In brief, the iron oleate complex was synthesized from 2mmol iron(III)acetyl acetonate [Fe(acac)3] that was suspended in 20mL of benzyl ether. After addition of 10mmol 1,2-hexadecanediol, 6mmol oleic acid and finally 6mmol oleylamine the reaction was started under argon atmosphere and heated to 250C under reflux for 30min.

General procedure: A solvothermal method was implemented to prepare CuFe2O4and Fe3O4 NPs. For the synthesis of Fe3O4 NPs, 4 mmol of Fe(acac)3 and 40 ml of triethylene glycol were mixed in a 200 ml round bottom flask connected to a reflux condenser. To homogenize thesolution, the temperature was increased to 100 C and maintainedat this temperature for 1 h. Afterwards the obtained homogenoussolutionwas transferred to a Teflon lined autoclave (75 ml capacity)and then placed in a furnace at 260 C for 24 h. Next, the mixturewas left to cool down to room temperature, which resulted in a black homogeneous dispersion containing magnetite nanoparticles.The obtained product was washed with acetone severaltimes using centrifugation. Then, the nanoparticles were put to dryin an oven at 50 C for 12 h. For the synthesis of CuFe2O4 NPs, thesame procedure was employed except that the stoichiometricamount of Cu(acac)2 was added to the triethylene glycol at the firstof synthesis process.
