Estimating sugar concentration in human blood serum using surface plasmon resonance (SPR)‎-based optical fiber sensor

الملخص EN

This paper presents the Surface Plasmon Resonance (SPR)-based plastic optical fiber sensor for estimating the concentration and refractive index of sugar in human blood serum.

(SPR) response curve for different samples of the blood serum was recorded in this work and exhibited a dip in the position of the resonance.it is found that the change in the refractive index of the sensing medium (blood serum) led to the change in the resonance wavelengths in the (SPR) response curve.

The resonance wavelength increase as the refractive index increase and this has been proven work at resonance wavelength (613 nm) the refractive index is (1.3628) and this value increased by increasing the resonance wavelength until it reaches the highest value it is (1.387) at resonance wavelength (734 nm).
