Summary: In this study, an electrochemical immunoassay method based on molybdenum disulfide (MoS2) was proposed to detect neuron-specific enolase (NSE) sensitively. The MoS2@Au nanozyme, formed by composite MoS2 and Au nanoclusters (Au NCs), was used to catalyze the decomposition of H2O2, which amplified the amperometric response and improved sensitivity. The detection range of this strategy was 0.1 pg·mL(-1)-10 ng·mL(-1) with a limit of detection of 0.05 pg·mL(-1). This sensing strategy showed potential for sensitive detection of NSE and can provide a theoretical basis and technical support for detecting other disease markers.
