Electrochemical techniques for fabricating tapered gold nanoantennas (tips) are discussed. In the paper, the tunable design of nanoantennas is demonstrated. Tip parameters such as a tip apex curvature, mesoscopic morphology, aspect ratio and enhancement factor can be varied with etching electrolyte and applied voltage. The low-cost method makes tipehnahced optical spectroscopy and microscopy feasible for routine optical measurements beyond the diffraction limit.
Key words: optical antennas / tip-enhanced Raman scattering / electrochemistry
