Outline of Final Research Achievements |
In this work, we were able to construct a nanospectroscopy system that can operate at 632.8 nm and 785 nm wavelengths and is housed in an environment control system to accommodate environment sensitive samples. The system was designed through the use of numerical simulations (FDTD and Mathematica) to obtain the optimal experimental parameters of the optics and probe (numerical aperture, laser illumination angle, tip tilt). A three-electrode electrochemical etching system was made to fabricate Au tips and a methodology was established to make these Au tips.

Academic Significance and Societal Importance of the Research Achievements |
It is important to develop nanospectroscopy systems that have both high spatial resolution and chemical sensitivity in order to study phenomena occurring at the nanometer scale. The development of a nanospectroscopy system in this project would help study both biological and non-biological samples.
