Outline of Final Research Achievements

The purpose of the research project is to demonstrate a small-size and low-cost sensor for the early diagnosis of diseases. A very sensitive detection technique of biomarkers is being developed using confined surface plasmons in nano-cavities operating on small sample volumes. Perfect light confinement in nano-cavities is possible when high-aspect-ratio U-shaped cavities are used to couple the cavity ridge hot spots with the scalable U-cavity resonances. Under the condition of coupled resonance, light is fully trapped in intense optical vortices and confined on the extended U-shaped cavity surfaces. This strong resonance generates sensitive reflectance dips. The light confinement in the nano-cavity is realized for a finite number of adjacent nano-cavities, so small sample volumes can be used. The reported perfect light confinement in the nano-cavities observed as a strong and sharp resonance is used in biochemical marker detection in a protein-ligand scheme.
