Surface Enhanced Raman Spectroscopy (SERS) Substrates
Raman signal intensity can be greatly enhanced when probing organic or biological molecules on substrates decorated with metallic nanostructures. Below are users' publications that report using our plasma instruments to fabricate SERS substrates and to remove probe molecules from SERS substrates without compromising the nanostructure morphology.
