In situ electrochemical surface enhanced Raman spectra (SERS) for an immobilized monolayer of a flavin analogue (isoalloxazine) at nanostructured silver surfaces are reported. Unique in the present study, the flavin is not directly adsorbed at the Ag surface but is attached through a chemical reaction between cysteamine adsorbed on the Ag surface and methylformylisoalloxazine. Even though the flavin is held away from direct contact with the metal, strong surface enhancements are observed. The…

SERS of beta-thioglucose adsorbed on nanostructured silver electrodes.
The results of this study show that beta-TG self-assembled at a silver electrode forms a hydrophobic film that may be used in biomimetic research to enhance interactions between the electrode and the hydrophilic portion of a model membrane, and to prevent interactions of proteins inserted into this membrane with the metal surface.
Catalytic oxidation of cinnamyl alcohol using Au-Ag nanotubes investigated by surface-enhanced Raman spectroscopy.
A comparison between changes in bulk composition and the nature of adsorbed species at the surface of the catalyst over time suggests that cinnamaldehyde is formed on the catalyst surface (metal-catalyzed oxidation) and benzaldehyde is probably formed in the bulk solution via a radical-chain pathway.
Fabrication of a bowl-shaped silver cavity substrate for SERS-based immunoassay.
A metal sandwich substrate bridged by an immunocomplex has been created for a surface enhanced Raman scattering (SERS)-based immunoassay, demonstrating that the new SERS substrate is suitable for the quantitative identification of biomolecules.
Redox molecule based SERS sensors.
It is shown that multiple sample spectroscopic ellipsometry gives access to the spectral dependence of the optical constants of single redox-molecule layers, and through it to the electronic resonances of the system.
Tuning the Surface-Enhanced Raman Scattering Effect to Different Molecular Groups by Switching the Silver Colloid Solution pH
It was concluded that it is possible to produce site- or molecule-specific metal colloids and to tune the SERS effect to certain functional groups of analytes by means of the pH of colloidal suspension.
SERS detection of polycyclic aromatic hydrocarbons on a bowl-shaped silver cavity substrate
Trace detection of polycyclic aromatic hydrocarbons (PAHs) by surface-enhanced Raman scattering (SERS) on a metal sandwich substrate bridged by 1,10-decanedithiolis is reported in this work. The
Operando electrochemical SERS monitors nanoparticle reactions by capping agent fingerprints
Nanomaterials are frequently employed in daily life goods, including health, textile, and food industry. A comprehensive picture is lacking on the role of the capping agents, added ligand molecules,
Using a silver-enhanced microarray sandwich structure to improve SERS sensitivity for protein detection
The proposed approach has potential for use in qualitative and quantitative detection of biomolecules and the SERS spectra of label-free proteins from the assembled sandwich have excellent reproducibility and high quality.
A spectroelectrochemical investigation of nanoparticle and molecular resonances in surface enhanced Raman scattering from crystal violet and malachite green
The interaction between nanoparticle plasmonic states and molecular electronic states is central to the large enhancements observed in surface-enhanced Raman scattering (SERS). In this work, we use a
