Enhancement of laser-induced fluorescence at 473 nm excitation with subwavelength resonant waveguide gratings.

Abstract

A dielectric subwavelength resonant waveguide grating was designed and fabricated in order to enhance fluorescence of biomolecules. More than 80 times higher laser-induced fluorescence yield was observed from enhanced green fluorescence protein on the structure when compared to same material on a flat surface.
