DNA tethers guide the self-assembly of colloidal metal nanoparticles into three-dimensional optical metamaterials. The observation of epsilon-near-zero behaviour in nanoparticle-based materials indicates that bottom-up assembly may be a viable solution to current challenges in the manufacture of metamaterials.
