Abstract
The fabrication and optimization of a surface plasmon resonance (SPR) based fiber optic sensor for glucose detection is reported in this work. The sensing probe was prepared using an arc-shaped single-mode fiber (SMF-28) coated with gold and then a layer of MXene, 2D material. The sensitivity performance of the sensor towards glucose analyte was investigated, first with gold-coated fiber SPR sensor and then with gold that was overlayed with Ti3C2 MXene. Different glucose concentrations ranging from 0.09 M to 1.30 M were tested and the spectral response of the sensor probe towards different concentrations of glucose was analyzed. It was found that the gold-coated fiber SPR sensor yields a sensitivity of 29.60 nm/M, and 33.06 nm/M for the gold-MXene coated fiber SPR sensor. The proposed study's findings show that gold with an overlay of MXene layer has provided a better sensitivity in glucose sensing applications.
