Data from: Esterification synthesis of iron oxide nanoparticle tracers for magnetic particle imaging (MPI)
Year: 2026
Type: dataset
Abstract: This repository contains the experimental data for a study of iron oxide nanoparticle synthesis via esterification to develop 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. Finally, (4) SQUID magnetometry data characterizing nanoparticle magnetic properties; and (5) magnetic particle imaging relaxometry and 2D scan data characterizing tracer sensitivity and resolution demonstrates the potential of the esterification synthesis route to develop size- and composition-controlled high-quality MPI tracers as an alternative to thermal decomposition synthesis. Researchers developing or characterizing magnetic nanoparticle tracers, evaluating nanoparticle synthesis routes, or benchmarking MPI tracer performance may find this dataset useful for comparison, reanalysis, or method development.
