Abstract

In this study, a label-free, specific and sensitive surface plasmon resonance (SPR) based competitive immunoassay was used for detecting Cd²⁺ in water samples. The standard curve of the method for Cd²⁺ was constructed in the concentration range of 0–1000 ng mL⁻¹. The values of IC₅₀ and the LOD of the assay were found to be 23.58 and 1.25 ng mL⁻¹. No cross-reactivity was found with other metal ions except Hg²⁺. The proposed method provides an alternative method for sensitive, specific and real-time determination of Cd²⁺ in real aqueous samples.
