dc.description.abstractCore–shell nano-structures were synthesized by adsorbing succinic acid on γ-Fe2O3 nanoparticles (hereafter referred to as core–shell nanoparticles or core–shells). Streptomycin was chosen as a model drug to attach on γ-Fe2O3 core–shells. Vibration spectroscopic data confirmed the specific adsorption of organic ligands (i.e., succinic acid or streptomycin) onto γ-Fe2O3 via bi-dentate, bi-nuclear complex. Possible molecular configurations between organic ligands and γ-Fe2O3 were examined by density functional theory (DFT) using Fe6(OH)18(H2O)6 ring cluster. The measured vibration frequencies and bond distances (i.e., Fesingle bondOsingle bondFe, Fesingle bondOw, and Fesingle bondOH units) of the optimized γ-Fe2O3 cluster matched well with the calculations.en
