Abstract

An AND logic gate-based Hg²⁺ ion colorimetric assay was constructed using the plasmonic and nanozyme dual signal channels of gold nanoparticles (AuNPs). This assay increased the judgment criteria for the identification of Hg²⁺ ions and effectively improved the accuracy of Hg²⁺ ion detection.
