Description
Cholesterol monolayers were deposited by the Langmuir-Blodgett (LB) technique on silicon wafers, glass slides, nano structured silicon wafers and nanostructured glass slides. These latter substrates are known as nanostructured substrates (SN) since they have deposited a silver film by the pulsed laser ablation technique (ALP). The films were characterized by the Raman spectroscopy technique to study whether the SERS effect (Surface Enhanced Raman Spectroscopy) presented by nanostructured substrates aids in the detection of thin films synthesized by the LB technique.
