We report the detection of oral cancer cells using Raman spectroscopy as a noninvasive diagnostic tool. Gold nanoparticles, synthesized by using sodium citrate as a reducing agent, were used as surface‐enhanced Raman scattering substrates to detect human oral squamous cell carcinoma cell lines (SAS and SCC4) with fibroblasts cell lines as the control. We have observed the characteristic Raman signal...
The substitution kinetics and specific binding modes of the dithiooxamide (dto) ligand at the metal surface have been investigated and interpreted on the light of theoretical and experimental Raman studies. By monitoring the vibrational properties of this ligand, it was shown that gold nanoparticles employed as surface‐enhanced effects (SERS) probes are strongly dependent on the coordination chemistry...
