Overview

Simulation-driven optimization reveals a borosilicate-based SPR sensor's effective detection of heavy metal ions in water, suggesting advanced environmental monitoring capabilities.

Key Points

  • The study aims to optimize a surface plasmon resonance sensor for detecting heavy metal ions in water efficiently.
  • Designed a borosilicate/Al/Al2O3/nanomaterial multilayer sensor.
  • Evaluated the optical performance using transfer-matrix modeling at 633 nm.
  • Analyzed sensitivity, FWHM, figure of merit, and limit of detection for various nanomaterials.
  • Borosilicate/Al/Al2O3/graphene oxide sensor exhibited angular sensitivities of up to 338°/RIU.
  • FWHM values around 2° and limit of detection approximately 10−5 RIU were achieved.
  • The sensor displayed clear angular shifts for heavy metal ion mixtures, validating its effectiveness for detection.
