Mechanically Tunable Lattice‐Plasmon Resonances by Templated Self‐Assembled Superlattices for Multi‐Wavelength Surface‐Enhanced Raman Spectroscopy (Small Methods 10/2021)

Inside Front Cover In article number 2100453, Kuttner, Liz-Marzán, Seifert and co-workers demonstrate mechano-optical nanostructures with reversibly tunable lattice-plasmon resonances consisting of self-assembled superlattices on stretchable substrates. Macroscopic mechanical strain allows a single lattice structure to be adapted both red-shifted blue-shifted excitation lines for maximum surface-enhanced Raman scattering. This post-assembly fine-tuning optical parameters enables rapid screening most-efficient superlattice designs.
