Nano-peapods: Magnetically responsive photonic nanochains have been produced by inducing chain alignment of uniform magnetic particles during their silica coating process and then allowing additional deposited silica to wrap entire structures. The optical diffraction of these nanochains can be switched on and off by applying magnetic fields.
