      abstract     = {Self-assembly of iron oxide nanoparticles (IONPs) into 1D
                      chains is appealing, because of their biocompatibility and
                      higher mobility compared to 2D/3D assemblies while
                      traversing the circulatory passages and blood vessels for in
                      vivo biomedical applications. In this work, parameters such
                      as size, concentration, composition, and magnetic field,
                      responsible for chain formation of IONPs in a dispersion as
                      opposed to spatially confining substrates, are examined. In
                      particular, the monodisperse 27 nm IONPs synthesized by an
                      extended LaMer mechanism are shown to form chains at 4 mT,
                      which are lengthened with applied field reaching 270 nm at
                      2.2 T. The chain lengths are completely reversible in field.
                      Using a combination of scattering methods and reverse Monte
                      Carlo simulations the formation of chains is directly
                      visualized. The visualization of real-space IONPs assemblies
                      formed in dispersions presents a novel tool for biomedical
                      researchers. This allows for rapid exploration of the
                      behavior of IONPs in solution in a broad parameter space and
                      unambiguous extraction of ​the parameters of the
                      equilibrium structures. Additionally, it can be extended to
                      study novel assemblies formed by more complex geometries of
                      IONPs.},
