I am an undergrad student from California performing research in Puerto Rico. I arrived to PR after ending my semester and it has been a great experience so far. I am currently performing research with the chemistry department in University of Puerto Rico Mayaguez, or as known here in PR, el Colegio. My project relates to the issue that currently there is a lot of contamination in water. Surface Enhanced Raman Spectroscopy, SERS, is a spectroscopic technique with strong Raman signal when molecules are attached to metallic structures, silver or gold.
