Surface-Enhanced Raman Spectroscopy
Our aim is to increase the enhancement factors of the SERS technique by developing novel designs and fabrication methods as well as using different excitation wavelengths ranging from UV to NIR. The objective of the project is to design, fabricate and analyze optical properties of metallic nanostructures and to perform Raman spectroscopy experiments of biomolecules. In particular, our current focus is deep-UV surface-enhanced resonance Raman scattering on aluminum nanostructures. We have recently demonstrated that this technique is a highly useful analytical technique for ultrasensitive and label-free detection of biomolecules in real time.
