Magnetic field guided colloidal assembly

We present here our recent studies on the magnetic-field-guided assembly of colloidal matter. Starting from a brief introduction of the magnetic interactions exerted on colloidal nanostructures, we discuss how magnetic fields drive their assembly into one-dimensional (1D), two-dimensional (2D), and three-dimensional (3D) ordered structures. This principle is further demonstrated in the assembly of colloidal matter on macroscopic and microscopic magnetized patterns with defined field strengths and spatial distributions.
