Label‐Free Characterization of Lipid Interfaces Using Plasmonic Gold Nanorods as Optically Active Nanosensors

Advanced Optical Materials, EarlyView.
A label‐free plasmonic nanosensor platform is presented based on single gold nanorods for the nanometric characterization of lipid interfaces. By correlating optical scattering signals with membrane packing and refractive index, this approach enables the detection of gel‐to‐fluid transitions in lipid interfaces, offering a robust, high‐resolution ...

The Role of Porosity in SERS

Advanced Optical Materials, EarlyView.
This review explores how engineered porous materials enhance surface‐enhanced Raman scatering (SERS) spectroscopy by synergizing analyte enrichment and electromagnetic field amplification. It is systematically evaluated four classes, nanoporous metals, plasmonic polymers, mesoporous silica, and metal‐organic frameworks (MOFs), highlighting their unique

Unraveling the Role of Surfactants in Micelle‐Templated Growth of Chiral Plasmonic Nanoparticles

Advanced Optical Materials, EarlyView.
Micelle template‐directed growth enables precise control over the chiroptical properties of gold nanorods. Comparison of surfactants with varying aliphatic tail lengths shows that longer tails increase groove inclination and reduce groove density. Optimized conditions for the longest‐tail surfactant (C18) yield slightly higher g‐factors than those ...

Illuminating Quantum Phenomena in 2D Materials: The Power of Optical Spectroscopy

Advanced Optical Materials, EarlyView.
Atomically thin 2D materials host quantum tunnelling, plasmonic and excitonic phenomena driven by reduced dimensionality and strong many‐body interactions. This review links these effects to state‐of‐the‐art optical probes—NSOM, pump–probe, CARS, TRR, and optical frequency comb spectroscopy—highlighting how their ultrahigh spatial–temporal resolution ...

On‐Chip Sensing with Slow Light Topological Cavities

Advanced Optical Materials, EarlyView.
A valley photonic crystal slow‐light sensor is demonstrated with up to 1.76‐fold shorter round‐trip path lengths than non‐slow‐light designs. The stronger light‐matter interactions in the slow‐light cavity sensor result in up to threefold higher sensitivity compared to the non‐slow‐light cavity sensor.
