Plasmonics and spectroscopy
This themed issue presents an exciting collection of articles on the studies of plasmonics and optical spectroscopy.
surface-enhanced Raman spectroscopy: a perspective on the current status
This perspective presents an overview of single-molecule surface-enhanced Raman scattering (sm-SERS).
Medical applications of surface-enhanced Raman scattering
Selected medical applications of SERS from the past few years are highlighted. Both aspects – the label-free SERS detection of biomedical samples as well as the use of SERS labels in medical applications – are covered.
Surface enhanced spectroscopy encompasses a broad field of linear and nonlinear optical techniques that arose with the discovery of the surface-enhanced Raman scattering (SERS) effect.
Nanogap structures: combining enhanced
Raman spectroscopy and electronic transport
Electrodes with nanogaps enable simultaneous plasmon-enhanced Raman spectroscopy and electronic transport at the molecular scale, probing optical and dissipative processes.
Recent developments and future directions in
SERS for bioanalysis
This perspective aims to highlight the recent developments in SE(R)RS for the detection of biomolecules.
Super-resolution imaging of interactions between molecules and plasmonic
Super-resolution imaging allows the location of plasmon-coupled molecular emission to be determined with <5 nm resolution.
Persistent misconceptions regarding SERS
SERS is some 35 years old, and the subject of over 11 000 articles.
Towards low-cost flexible substrates for nanoplasmonic sensing
This perspective focuses on the recent developments and future directions for the fabrication of flexible nanoplasmonic devices for sensing applications based on SERS and LSPR.
Model of the photoexcitation processes of a two-level molecule coherently coupled to an optical antenna
We theoretically elucidate peculiar photoexcitation processes of a two-level molecular system coherently coupled with an antenna system having a significant dissipation.
Sensing dielectric media on the nanoscale with freely oriented gold
We demonstrated that the scattering and luminescence patterns of freely oriented GNRs can be used for sensing dielectric media.
Plasmonics in the ultraviolet with the poor metals Al, Ga, In, Sn, Tl, Pb, and Bi
The relative merits “poor metal” nanoparticle systems for achieving plasmonic behavior in the ultraviolet spectral region are assessed.
Raman enhancement by plasmonic excitation of structurally-characterized metal clusters: Au8, Ag8, and Cu8
The structure-dependent plasmonic enhancement of Raman spectra indicates a possibility of structurally-characterized small clusters for sensitizing various optical processes.
SERS reveals the specific interaction of silver and gold nanoparticles with hemoglobin and red blood cell components
The specific interaction of gold and silver nanoparticles with hemoglobin and red blood cells in the context of nanotoxicity was investigated by surface-enhanced Raman scattering.
LSPR properties of metal
nanoparticles adsorbed at a liquid–liquid interface
We present the theoretical LSPR-based optical properties and SERS properties of gold nanoparticles at the water–oil interface based on 3D-FDTD numerical simulations, including far field and near field features.
Probing the dielectric response of
graphene via dual-band plasmonic nanoresonators
We present experimental and simulated results exploring the dielectric response and potential for chemical sensing applications of a Au concentric disk ring cavity array integrated with an encapsulating graphene overlayer.
Improving correlated SERS measurements with
scanning electron microscopy: an assessment of the problem arising from the deposition of amorphous carbon
Improving correlated SEM/SERS studies.
SERS-based immunoassay of tumor marker VEGF using DNA aptamers and silica-encapsulated hollow gold nanospheres
We report a novel SERS-based sandwich immunoassay using DNA aptamer and a gold-patterned microarray for sensitive detection of VEGF angiogenesis protein markers.
Phosphate mediated adsorption and
electron transfer of cytochrome c. A time-resolved SERR spectroelectrochemical study
Inorganic phosphate and ATP mediate high affinity binding of cytochrome c on positively charged SAMs, with preservation of the native protein structure and rendering an average orientation that guarantees efficient pathways for direct electron transfer.
