Abstract

Superparamagnetic magnetite nanoparticles can be assembled into 1D arrays by a capillary-bridge mediate assembly approach, inspired by the Earth's magnetic field perception in nature. These 1D arrays possess strict alignment, precise position and high aspect ratio, yielding highly anisotropic magnetization characteristic.

Keywords: 1D structures; anisotropic magnetism; bioinspired; capillary bridges; self-assembly.
