Outline of Final Research Achievements

In this project, I conducted the investigation of enhanced optical signals from fluorescent molecules dispersed on artficial nanostructures, called plasmonic metasurfaces, and attained the more than 2000-fold optical signals in comparison with reference signals from a non-enhancing configuration. This uniform and significant enhancement effect is a great step towards a new method for optical detection of very low-density molecules.
