Data from: Esterification synthesis of iron oxide nanoparticle tracers for magnetic particle imaging (MPI)

The dataset includes: (1) Fourier-transform infrared (FTIR) spectra and tracked functional-group peak positions used to monitor reaction progress; and (2) transmission electron microscopy (TEM) for particle size measurements characterizing nanoparticle diameter and morphology across a range of synthesis conditions.

The variables tested include temperatures (290–350 °C), precursor addition rates (0.025–2.5 mmol Fe min -1), and three iron oleate precursor compositions (Fe(II), Fe(III), and a 1:2 Fe(II):Fe(III) mixture). For larger nanoparticles from the iron oleate precursor study, additional nanoparticle characterization included (3) X-ray diffraction (XRD) patterns and ⁵⁷Fe Mössbauer spectra to identify iron oxide crystal phase and composition.
