摘要: We report a new approach to surface plasmon resonance (SPR) biosensing based on spectroscopy of multiple plasmons special multi-diffractive grating coupler. In this approach, the binding event at SPR coupler is simultaneously observed by different wavelengths, which makes it possible determine binding-induced changes in refractive index distribution sensor surface. demonstrate potential concept model experiment three-surface used background variations and thickness bovine serum albumin multi-layer grown
