Popis:	It is demonstrated that ultrahigh sensitivity of glucose refractive index measurement can be achieved via surface plasmon resonance excitation in which the phase difference between p- and s-polarized reflected waves is monitored as a function of the incident angle. Sensitivity with values down to the order of 10−8 is obtained by performing the measurements at optimal incident wavelengths. This represents an order of magnitude improvement compared to the previously reported values in the literature.
