Abstract: Magnetic field can be employed as an effective tool for assembling nanostructured colloidal particles into functional materials, controlling their properties, and fabricating novel nanoscale devices. The key is to induce well controlled particle-external field interactions or particle-particle magnetic interactions. In this presentation, I will use a number of examples recently developed in my group to demonstrate that magnetic field can be utilized to dynamically tune the optical properties of nanostructured materials, such as diffraction of photonic crystals, birefringence of liquid crystals, and surface plasmon resonance of metallic nanostructures. By taking advantage of our tailored syntheses of well defined nanostructured building blocks, we show that such dynamic tuning can be realized through effective control over the assembly and disassembly behaviors or the orientation of the nanostructures using magnetic fields.
