Processing SPR signals can involve processing a first and second signal indicative of an intensity of light, received from a conductive layer at which SPR has occurred, as a function of angle of incidence, reflection or diffraction at the layer. The first and second signals each have two dips corresponding to a respective wavelength of the light at a respective angle at which surface plasmon resonance occurs for the respective wavelength and a peak between the two dips. The processing includes deriving a first and second value of a quantity indicative of signal magnitudes in the region of the peak. The first and second values can be compared to detect a change in refractive index at the layer after the first signal and before the second signal was captured."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Enhanced Surface Plasmon Resonance method","description":"The disclosure relates to processing SPR signals, in particular signals obtained by illuminating a conductive surface with light at two wavelengths.
