Nanophotonics relies on precise control of refractive index (RI) which can be designed with metamaterials. Plasmonic superstructures of nanoparticles (NPs) can suggest a versatile way of tuning RI. However, the plasmonic effects in the superstructures demand 1 nm‐level exquisite control over the interparticle gap, which is challenging in a sub‐wavelength NPs. Thus far, a large‐area demonstration has...
Supracolloidal hybrids: Soft polymer‐based Janus micelles provide excellent stabilization for multi‐walled carbon nanotubes (see scheme) in a variety of solvents, including water. The size ratio of the micelle′s stabilizing corona to adsorbing corona (Janus balance) is decisive for good physisorption and stabilization. The supracolloidal interaction preserves the structural integrity of the nanotubes,...
