TL;DR: Experimental result shows that, with the star-shaped nanoparticles, the HMM-based substrate yields 30% higher Raman intensity for near infrared SERS operation than the silver film- based substrate does.

TL;DR: A periodic metallic–dielectric nanorod array which consists of Si nanorods coated with 30 nm Ag thin film set in a hexagonal configuration is fabricated and characterized and shows an average sensitivity when applied to a refractive index sensor.

TL;DR: Investigation of a highly sensitive and tunable plasmonic refractive index sensor that is composed of a metal-insulator-metal waveguide with a side-coupled nanoring, containing silver nanorods using the finite element method reveals that the presence of silver Nanorods in the nanoring has a significant impact on sensitivity and tunability performance.

TL;DR: The results reveal that both the size of defects in wider rectangular cavity and the length of narrower rectangular cavity are primary factors increasing the sensitivity performance, which is the highest sensitivity reported in plasmonic MIM waveguide-based sensors to the authors' knowledge.

TL;DR: The proposed structure with a gathering of four metal-shell nanorods using a cross-hair operating at visible and near-infrared regions gives a novel inspiration for the design of a tunable dual-band PPA, which can be exploited for plasmonic sensor and other nanophotonic devices.
