Title: Enhanced multicolor fluorescence in bioimaging using deep-ultraviolet surface plasmon resonance

Enhanced multicolor fluorescence has been achieved using deep-ultraviolet surface plasmon resonance (DUV-SPR) on an aluminum thin film using the Kretschmann configuration. The film thickness and the incident angle of the light were optimized by calculations using the Fresnel equations. The presence of a surface oxide layer was also considered in the calculations. Experimental measurements showed that DUV-SPR led to a strong enhancement of the fluorescence intensity from both quantum dots and dye-labeled cells.
