ABSTRACT
We report the design and characterization of a one-dimensional photonic crystal slab incorporating a nanorod-structured TiO2 high index layer. The photonic crystal is designed to function as an optical resonator at the wavelength of a laser used to excite fluorescence emission and the highly porous TiO2 film, not only increases the surface area of the device but more importantly allows fluorophores to penetrate into the most intense region of the resonance-enhanced near electric fields. The design shows an enhancement of 193-fold in fluorescence intensity for the detection of cyanine 5-labeled streptavidin in comparison to an unpatterned glass slide.
