Optical fiber biomedical sensor based on surface Plasmon resonance for Candida detection

الملخص EN

In this work, optical fibers were designed and implemented as a medical sensor based on surface Plasmon resonance (SPR) to estimate different refractive indices and (Candida) concentrations and improve the endoscope's performance.

Using multi-mode and single-mode optical fibers deposited by 40 nm thickness gold metal deposition for the sensing area, in practice, it was found that when the refractive index of the sensitive medium increases, the length of the resonant wave increases due to the decrease in energy.
