We are interested in understanding and exploiting plasmonic affects to develop chemical sensors. The group is the first to develop a truly functional multimode fiber-optic surface plasmon resonance sensor for in situ applications and midinfrared surface plasmon resonance platform that is fully integrated into the sample compartment of an FT IR.
Current research directions involve developing methods for large molecules and small molecule detection in complex matrices. Novel surface coatings, such as disodium salt linkers and environmentally responsive polymers , are incorporated with the SPR sensors to increase sensitivity and selectivity. The "gap mode" between two plasmonic structures is also being investigated as a method to enhance sensitivity of analyses.
