Surface plasmon resonance spectrometer sensor using super-period metal nano-grating

摘要

Summary form only given. Periodic metal nanostructures support localized surface plasmon resonances, which has been extensively investigated for biochemical sensing applications. Surface plasmon resonances were previously measured by using optical spectrometers in either transmission or reflection mode. By creating metal nanostructure diffraction gratings, surface plasmon resonance can be measured in the diffraction mode with a linear detector array without using an optical spectrometer. In this talk, I will present a new surface plasmon resonance sensor platform using super-period metal nanostructures. By using super-period metal nanostructures, surface plasmon resonance spectrometer sensor can be built for integrated biochemical sensing. Being able to measure surface plasmon resonances in the diffraction mode opens a new avenue for integrated surface plasmon resonance spectroscopic sensing.
