Abstract
En 中文
• Developed a low-cost optical fiber-based SPR sensor for Hg²⁺ detection using CuNPs and FeNPs. • CuNPs and FeNPs were synthesized via the environmentally friendly exploding wire (EW) method. • The CuNPs-modified probe exhibited superior sensitivity (1.29 nm/µM) with an LOD of 0.40 µM. • The proposed sensor demonstrates strong potential for real-time water quality monitoring.
