Ultranarrow Linewidth Coupling Resonance in Flexible Plasmonic Nanopillar Array for Enhanced Biomolecule Detection (Adv. Mater. Interfaces 27/2022)

Plasmonic Nanostructure Sensor In article number 2201011, Shuwen Chu, Yuzhang Liang, and co-workers experimentally demonstrate a flexible plasmonic nanostructure sensor based on a large-scale periodic array of nanopillars. The structure utilizes the coupling of Wood's anomaly and Fabry-Perot modes to generate an ultra-narrow plasmon resonance mode with high sensing figure of merit (FOM), providing an effective strategy for label-free biomolecular sensing with low cost, high sensitivity and high throughput.
