✦ Synopsis

An electrochemical procedure for obtaining surface-enhanced Raman scattering (SERS) spectra of polythiophene Ðlms is described. During the electropolymerization process, which consists of using silver dodecylsulfate micellar aqueous solution mixed with bithiophene and silver cations are reduced, thus giving metallic silver par-LiClO 4 , ticles embedded within the polybithiophene (PbT) Ðlm. Both doped and undoped PbT species display SERS spectra with enhancement factors varying between 40 and 200 with respect to the Ðlm prepared in sodium dodecylsulfate (i.e. without silver cations). Vibrational characterization of both doped and undoped species is then carried out and the polymer structural defects are evaluated.

Surface enhanced Raman scattering (SERS) was used to study phospholipid monolayers transferred by the Langmuir-Blodgett (LB) technique to SERS active substrates. These substrates, which were constituted of gold colloidal nanoparticles bound to polysilane films grafted onto glass plates, showed a uni
