A detailed comparative analysis is carried out between two fiber optic surface plasmon resonance (SPR) sensor probes with different bimetallic configurations. One consists of a step arrangement of thin layers of silver and gold. Another one consists of alloy layer formed of spherical silver and gold nanoparticles. Their sensitivity and detection accuracy are compared. Better configuration is predicted with proper logics and rationales.
