<div>The approach to inhibit endogenous peroxidases by elevated concentrations of hydrogen peroxide while maintaining the high peroxidase-mimicking activity of Au@Pt nanozymes was developed. The approach facilitates selective and highly-sensitive detection of peroxidase-mimicking nanozyme nanozymes in the background of endogenous peroxidases. Au@Pt nanozyme was used as the colorimetric and catalytic label in lateral flow immunoassay of an important plant pathogen – potato virus X. The inhibition of endogenous peroxidases in plant extracts and selective detection of Au@Pt nanozyme provides the lowest limit of detection among immunochemical assays of potato virus X (up to 500 times lower compared to the assay with conventional gold nanoparticles). </div><div>The proposed approach uses the fundamental principle of enzyme inhibition by the substrate. It is universal and applicable to all matrixes with peroxidase activity. </div>

In this study, a thiol-modified aptamer was immobilized on a gold nanoparticle-modified molybdenum disulfide composite material (MoS2@AuNPs), which could remove the interference of physical adsorption and reduce false positive signals.
