HARRICK PLASMA

Surface Enhanced Raman Spectroscopy (SERS) Substrates

In SERS, Raman signal intensity can be greatly enhanced when probing organic or biological molecules on substrates decorated with metallic nanostructures. Plasma treatment may be applied towards fabricating such SERS substrates and removing probe molecules from SERS substrates without compromising the nanostructure morphology.
