Abstract
A novel dual-channel surface plasmon resonance sensor is described which uses a high refractive index overlayer to spectrally separate sensing channels, allowing for their simultaneous interrogation using a single spectrograph. A theoretical analysis of the sensor is presented as well as experimental results demonstrating its capability as a biosensor.Keywords
