The synthesis and characterisation of magnetic nanoparticles and their interaction with a zinc phthalocyanine

► A range of magnetic nanoparticles were synthesized and characterized. ► Zinc phthalocyanine (ZnPc) ligand exchange was accomplished. ► ZnPc was successfully employed as a stabilizer for NP synthesis. ► Significant Q band red shifting observed in the UV/Vis and fluorescence spectra.
