Enhanced performance of SPR sensor using PbTiO3 and BlueP/WS2 on Al-Co bimetal for urine glucose sensing application
This numerical work focuses on the excellent performance of urine glucose level detection under a SPR-based sensing technology. The low-cost plasmonic metal Al based hybrid structure (Al-bimetal-PbTiO3-BlueP/WS2) is suggested for the modified Kretschmann design, which is found to offer accurate gluc...

| description | This numerical work focuses on the excellent performance of urine glucose level detection under a SPR-based sensing technology. The low-cost plasmonic metal Al based hybrid structure (Al-bimetal-PbTiO3-BlueP/WS2) is suggested for the modified Kretschmann design, which is found to offer accurate glucose detection along with reduced sensor fabrication cost. The bimetallic combination of Co, Ni, and Pt along with Al thin film is suggested to inhibit the oxidation of Al and numerically optimized for enhance sensing performance. The inclusion of 2D material such as a BlueP/WS2 as a suitable cover layer is found not only to protect the sensor but also to provide good interaction with the sensing medium to increase sensor sensing functionality. Results shows upon suitably optimizing each layer thickness enhanced sensitivity as high as 321°/RIU, 326.8°/RIU, 349.6°/RIU, 380.26°/RIU, and 525.48°/RIU for the glucose concentrations of 0.625 g/dL, 1.25 g/dL, 2.5 g/dL, 5 g/dL, and 10 g/dL, respectively. This simplified configuration and high sensitivity make it quite suitable for obtaining a more accurate identification of urine glucose levels. |
