Surface-Enhanced Raman and Fluorescence Spectroscopy with an All-Dielectric Metasurface

The Journal of Physical Chemistry C, 2018
Plasmonic substrates play a crucial role in the confinement and manipulation of localized electromagnetic fields at the nanoscale. The large electromagnetic field enhancement at metal/dielectric interfaces is widely exploited in surface-enhanced fluorescence (SEF) and surface-enhanced Raman scattering (SERS) spectroscopies.

Surface enhanced bacterial fluorescence and enumeration of bacterial adhesion

Biofouling, 2012
The use of flow displacement systems for studying initial bacterial adhesion to surfaces is mostly confined to transparent substrata. The objective of this study was to investigate a method based on macroscopic fluorescence imaging to enumerate adhering fluorescent bacteria on non-transparent substrata, real-time and under flow. To this end, a stepwise

Surface-Enhanced Fluorescence of Rhodamine 6G on the Assembled Silver Nanostructures

Journal of Nanoscience and Nanotechnology, 2011
The fluorescence emission and enhancement of Rhodamine 6G on the silver island films (SiFs) with and without 4-Aminothiophenol molecules have been investigated. It was found that the SiFs without 4-Aminothiophenol molecules (PATP) have less contribution to the fluorescence enhancement. However, when PATP molecules as a spacer were deposited on the SiFs,

Immunoassay quantification using surface-enhanced fluorescence (SEF) tags

The Analyst, 2017
A fluorescence immunoassay based on surface-enhanced fluorescence (SEF) was introduced. The use of SEF tags may provide advantages over regular organic dyes for biomedical assays.

Surface-enhanced Raman and fluorescence joint analysis of soil humic acids

Analytica Chimica Acta, 2008
Surface-enhanced Raman scattering (SERS) and surface-enhanced fluorescence (SEF) combined emissions were used in this work to the analysis of humic acids (HA). This study examined HA structure at different pH and HA concentrations and assessed the structural differences taking place in HA as a result of various amendment trials.

Surface enhanced fluorescence

Journal of Physics D: Applied Physics, 2007
Fluorescence is widely used in optical devices, microscopy imaging, biology, medical research and diagnosis. Improving fluorescence sensitivity, all the way to the limit of single-molecular detection needed in many applications, remains a great challenge.
