Large‐Area Metallic Nanohelices for Engineering Optical Chirality

Small, Volume 22, Issue 13, 3 March 2026.
By exploiting the nanoscale engineering of residual stresses in metallic thin films, this method enables scalable fabrication of submicrometer metallic helices with tunable geometry and material versatility. The resulting structures exhibit pronounced chiroptical responses across the mid‐ to near‐infrared range, offering a robust platform for chiral ...

Plasmonic Chiral Metasurfaces for Real‐Time Refractive Index Sensing and In Situ Monitoring of Thin Film Growth

Small Science, Volume 6, Issue 3, March 2026.
A sensor based on a plasmonic chiral metasurface is fabricated via Layer‐by‐Layer assembly and grazing incidence spraying of silver nanowires, and integrated in a flow‐cell. It enables stable, real‐time circular dichroism measurements with high sensitivity toward refractive index changes of the surroundings.

Single‐Molecule Imaging and Spectroscopy Enables Quantification of Location‐Dependent Light–Matter Interactions on Nanoantennas

Small Science, Volume 6, Issue 3, March 2026.
The fluorescence intensity as well as the spectral shape of the emission of single dye molecules strongly depend on the molecules’ exact position relative to plasmonic nanoparticles in hybrid systems. By point‐spread function modification analysis, the vertical binding location of single fluorophores on gold nanocones is obtained and correlated to both

Direct Photochemical Patterning of Lithium Niobate Structures for Scalable Nonlinear Optical Metasurfaces

Small Science, Volume 6, Issue 3, March 2026.
Photochemical metal–organic decomposition (PMOD) enables scalable patterning of lithium niobate (LN) metasurfaces under ambient conditions, eliminating the need for cleanrooms or harsh etching. This bottom‐up approach produces complex, diverse, and size‐tunable polycrystalline LN patterns.

Tunable Core–Shell Metal Alloy Pillar Design in Vertically Aligned Nanostructures Toward Multifunctionality

Small Science, Volume 6, Issue 3, March 2026.
Core–shell alloy‐based BaTiO3/Au–Cu–Co–Ni vertically aligned nanocomposites exhibit tunable nanopillar morphologies governed by interfacial energetics. A temperature–time–transformation diagram predicts nanopillar evolution, while structure–property relationships link morphology with controllable optical anisotropy, hyperbolic dispersion, magnetic ...
