Abstract :
A capillary-based surface plasmon resonance sensor is presented. Glass capillaries internally coated with Au are radially illuminated with focused laser light that strikes the interior capillary surface and exits the capillary at angles that vary with the interior incident angle. Measurement of the exit light provides reflectivity against angle spectra useful for chemical sensing
