N2 - Flame Spray Pyrolysis (FSP) was used to synthesize γ-Fe 2O3 and SiO2/γ-Fe2O 3 nanoparticles of different sizes (dBET = 5-60 nm). Bare γ-Fe2O3 displays unique hexagonal/octagonal disc-shaped nanoparticles, while different morphology of SiO2/ γ-Fe2O3 nanoparticles could be produced by varying the ratio of silica and iron precursors during synthesis. The particles were predominantly superparamagnetic at room temperature. The understanding on how different nanostructures were formed was obtained through characterisation of their properties using Transmission Electron Microscopy, X-ray Diffraction, Atomic Force Microscopy, N2 adsorption, and Superconducting Quantum Interference Device magnetometer. The study is particularly useful in order to tailor the properties of these magnetic nanoparticles during synthesis for bio-related applications.
