Detection of Molecular Vibrations of Ciprofloxacin Using Flexible Plasmonic Active Substrates as Surface-Enhanced Raman Scattering (SERS) Biosensors

Plasmonic substrates for surface enhanced Raman scattering.

As an advanced analytical tool, surface-enhanced Raman scattering (SERS) has broad applications in identification of colorants in paints and glazes, hazard detection to ensure food safety, biomedicine and diagnosis, environmental monitoring, detection of explosives and forensic science. In this review, main types of plasmonic substrates, which include solid substrate with metallic nanostructure...

Asphaltene detection using surface enhanced Raman scattering (SERS).

Surface enhanced Raman spectroscopy using a gold substrate and excitation at 514 nm can detect sub parts per million quantities of asphaltene and thereby petroleum. This simple format and sensitivity make it transformative for applications including sample triage, flow assurance, environmental protection and analysis of unique one of a kind materials.

Macroscale Plasmonic Substrates for Highly Sensitive Surface-Enhanced Raman Scattering**

Surface-enhanced Raman scattering on tunable plasmonic nanoparticle substrates.

Au and Ag nanoshells are investigated as substrates for surface-enhanced Raman scattering (SERS). We find that SERS enhancements on nanoshell films are dramatically different from those observed on colloidal aggregates, specifically that the Raman enhancement follows the plasmon resonance of the individual nanoparticles. Comparative finite difference time domain calculations of fields at the su...
