Insight into synthesis and characterisation of Ga_0.9Fe_2.1O₄ superparamagnetic NPs for biomedical applications.

ABSTRACT: A Ga³⁺-substituted spinel magnetite nanoparticles (NPs) with the formula Ga_0.9Fe_2.1O₄ were synthesized using both the one-pot solvothermal decomposition method (TD) and the microwave-assisted heating method (MW). Stable colloidal solutions were obtained by using triethylene glycol, which served as a NPs stabilizer and as a reaction medium in both methods. A narrow size distribution of NPs, below 10 nm, was achieved through selected nucleation and growth. The composition, structure, morphology, and magnetic properties of the NPs were investigated using FTIR spectroscopy, thermal analysis (TA), X-ray diffraction (XRD), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), and magnetic measurements. NPs with the expected sp
