“…320–323 The resulting dipole–dipole interactions drive the self-assembly of diamagnetic particles into 1D colloidal chains, 2D and 3D superstructures with increasing external magnetic field. 324–326 1D architectures with multiple configurations assembled from magnetic and nonmagnetic particles were created in ferrofluids by tuning the strength of the magnetic field, the concentration of ferrofluids, and the number of magnetic and nonmagnetic building blocks (Fig. 5g and h).…”

“…Jadav et al have used magnetic nanofluid to induce bi-dispersed suspension of non-magnetic particles into colloidal chain, triangle, rectangle, and ring-flower configurations [ 18 ]. Abelmann et al have demonstrated that 3D structures can self-assemble by taking advantage of dipolar forces [ 19 ].…”

Self-Assembly Magnetic Micro- and Nanospheres and the Effect of Applied Magnetic Fields

The impact of in-plane and perpendicular magnetic fields on the spatial arrangement of superparamagnetic nanospheres is explored. We utilize nanosphere self-organization methods like Spin Coating and Drop-Casting in the presence of magnetic fields. In this way, the additional parameter of the long range magnetic dipolar interactions is introduced to the competing nanosphere–surface and nanosphere–nanosphere interactions, which control order and agglomeration. We present a comparative analysis of the self-assembly characteristics with respect to the different methods and the effect of the applied field in different directions. Under zero field perfect hexagonal arrays can be obtained by spin coating. Parallel applied fields tend to create directional patterns, while perpendicular favor 3D-accumulation.
