Raman and infrared (IR) spectroscopy are powerful analytical techniques, but have
intrinsically low detection sensitivity. There have been three major steps (i) to advance the …

Incorporating photonic crystals with nanoplasmonic building blocks gives rise to novel
optoelectronic properties that promise designing advanced multifunctional materials and …

Total internal reflection (TIR) optical spectroscopies have been widely used for decades as
non-destructive and surface-sensitive measurements of thin films and interfaces. Under TIR …

To improve the sensitivity of disease biomarker detection, we proposed a high-performance
surface-enhanced Raman spectroscopy (SERS) chip integrated with a micro-optical system …

A novel flexible Surface-enhanced Raman Spectroscopy (SERS) chip integrated with
microlens was proposed and designed, which consisted of PDMS film, planoconvex …

Metal nanostructures with the configurations of narrow gaps or sharp tips attract plenty of
researchers due to their superior performances in plasmonic sensing and surface-enhanced …

Experimental data for waveguide-coupled surface-plasmon-polariton (SPP) cones
generated from dielectric waveguides is presented. The results demonstrate a simpler route …

The surface‐enhanced Raman scattering (SERS) effect was discovered by Richard Van
Duyne et al. in 1977. He and coworkers also first utilized an innovative strategy that used …

Silver nanoparticles (AgNPs) show an extraordinary strong interaction with light, which
enables confinement and field enhancement at the nanoscale. However, despite their …

The analysis of critical dimensions of nanostructured areas should ideally give both their
size with nanometer resolution and the size distribution over a large area, two contradicting …
