Personal profile

Area of Expertise

My research interests cover fluorescence spectroscopy and its applications in biochemistry and biology. I am developing advanced fluorescence-based techniques for ultra-sensitive detection of analytes and biomedical agents. In particular, we have developed a FRET-based method for the selective detection of a metalloproteinase 9 enzyme (MMP-9) and micro RNAs. The enhanced detection of minute amounts of dye molecules has been achieved with a Metal Enhanced Fluorescence (MEF). Several plasmonic platforms have been developed and tested for MEF. These include silver island films, silver fractals, and silver nanowires deposited on glass/sapphire substrates. We demonstrated several hundredfold enhancements of the fluorescence signals by using our plasmonic platforms. We also applied surface plasmon coupled emission (SPCE) in fluorescence microscopy. SPCE transforms an isotropic fluorescence emission into a directional, fully polarized radiation. The SPCE radiation preserves all spectral properties of used fluorophores and offers a significant reduction of unwanted fluorescence background because of minimization of the excitation volume.
