Fabrication and Characterization of Substrate Materials for Trace Analytical Measurements by Surface Enhanced Raman Scattering (SERS) Spectroscopy Technique
| Title: | Fabrication and Characterization of Substrate Materials for Trace Analytical Measurements by Surface Enhanced Raman Scattering (SERS) Spectroscopy Technique |
| Author: | Vabbilisetty, Pratima |
| Description: | The detection of various compounds using Surface enhanced Raman Scattering (SERS) from colloidal suspensions of silver and gold colloids has been attempted. Different substrates have been utilized and SERS spectra for R6G, creatinine, imidazole and benzoic acid have been evaluated as a function of time. SERS investigations have been performed using model compounds to allow comparison between the substrates. Different concentrations of R6G have been used for the valuation of the analytical capabilities. Silver and gold colloids have been prepared and used for SERS measurements and for the fabrication of substrates having a layer of immobilized metal nanoparticles. |
