generation
of anisotropic nanostructures by a magnetic field pulse in liquid
matrices by balancing the thermal energy, short-range attractive and
long-range repulsive forces, and dipole–dipole interactions
using a specially tailored polymer shell of nanoparticles. The locking
mechanism is used to precisely regulate the dimensions of self-assembled
magnetic nanoparticle chains and to generate and disintegrate three-dimensional
(3D) nanostructured materials in solvents and polymers.
