Sustained and Cost Effective Silver Substrate for Surface Enhanced Raman Spectroscopy Based Biosensing

Biosensing Based on Surface-Enhanced Raman Spectroscopy by Using Metal Nanoparticles

Surface-enhanced Raman spectroscopy (SERS) is a promising tool in the analytical science because it provides good selectivity and sensitivity without the labeling process required by fluorescence detection. This technique consists of locating the target analyte on nanometer range of roughed Au-nanoparticles. The presence of the metal nanoparticles provides a tremendous enhancement to the result...

Silver Nanoparticle Monolayers for Plasmonics and Surface-Enhanced Raman Spectroscopy

Polytetrafluorethylene-Au as a substrate for surface-enhanced Raman spectroscopy

This study deals with preparation of substrates suitable for surface-enhanced Raman spectroscopy (SERS) applications by sputtering deposition of gold layer on the polytetrafluorethylene (PTFE) foil. Time of sputtering was investigated with respect to the surface properties. The ability of PTFE-Au substrates to enhance Raman signals was investigated by immobilization of biphenyl-4,4'-dithiol (BF...

Silver Nanostar Patterned Substrate for Label-Free Characterization of Breast Cancer Cells based on Surface-Enhanced Raman Spectroscopy

Characterization of cancer cells is important in case of personalized cancer therapy. Cells can be characterized based on their surface marker expression level using fluorescence or surface-enhanced Raman spectroscopy (SERS) method, but in both cases its needed additional labeling with fluorescent or Raman dyes, those may cause cellular cytotoxicity. In this study, we report silver (Ag) nanosta...
