Self-aligned colocalization of 3D plasmonic nanogap arrays for ultra-sensitive surface plasmon resonance detection.
TL;DR: extremely sensitive plasmonic detection that was performed label-free based on the colocalization of target DNA molecules and electromagnetic hot spots excited at 3D nanogap arrays to achieve significantly amplified optical signatures that lead to sensitivity enhancement in terms of detectable binding capacity in reference to conventional thin film-based surface plasMon resonance detection.

TL;DR: NLS can be useful for moving objects that have a high labeling density or for performing fluctuation spectroscopy in small volumes, and may allow "super-resolution on demand" by customizing nanoantenna structures for specific resolution needs.

Extraordinary Transmission‐based Plasmonic Nanoarrays for Axially Super‐Resolved Cell Imaging
Jong-ryul Choi,Kyujung Kim,Kyujung Kim,Youngjin Oh,Ah Leum Kim,Sook Young Kim,Jeon Soo Shin,Donghyun Kim +7 more
TL;DR: Extraordinary transmission based axial imaging (EOT‐AIM) for cell microscopy is reported and experiments were performed for the measurement of the axial distribution of ganglioside in mouse macrophage cells using FITC‐conjugated cholera toxin subunit B.

Grating-based surface plasmon resonance detection of core-shell nanoparticle mediated DNA hybridization
TL;DR: Experimental results measured for hybridization of 24-mer single-stranded DNA oligomers suggest that core-shell nanoparticles (CSNPs) on gratings of 400 nm period provide enhanced optical signatures by 36 times over conventional thin film-based SPR detection.
