“…Organophosphorus pesticides (OPPs), which represent 33% of available pesticides in developed countries and 50–60% in developing countries, 1 are the most extensively used pesticides worldwide to protect crops. However, the excessive use of OPPs leads to residues in food 2,3 and the natural environment.…”

“…To highlight the progress in this field, here we intend to summarize the principles, methods, and applications of nanozyme-based sensors for pesticide and ChE detection. What should be stated is that although there are a number of thematic reviews on pesticide and related biomarker biosensing [15,[37][38][39][40][41][42][43][44], no reviews focus on the emerging applications of nanozymes in pesticide biosensors. Our contribution is expected to fill in the gap.…”

To improve the output and quality of agricultural products, pesticides are globally utilized as an efficient tool to protect crops from insects. However, given that most pesticides used are difficult to decompose, they inevitably remain in agricultural products and are further enriched into food chains and ecosystems, posing great threats to human health and the environment. Thus, developing efficient methods and tools to monitor pesticide residues and related biomarkers (acetylcholinesterase and butylcholinesterase) became quite significant. With the advantages of excellent stability, tailorable catalytic performance, low cost, and easy mass production, nanomaterials with enzyme-like properties (nanozymes) are extensively utilized in fields ranging from biomedicine to environmental remediation. Especially, with the catalytic nature to offer amplified signals for highly sensitive detection, nanozymes were finding potential applications in the sensing of various analytes, including pesticides and their biomarkers. To highlight the progress in this field, here the sensing principles of pesticides and cholinesterases based on nanozyme catalysis are definitively summarized, and emerging detection methods and technologies with the participation of nanozymes are critically discussed. Importantly, typical examples are introduced to reveal the promising use of nanozymes. Also, some challenges in the field and future trends are proposed, with the hope of inspiring more efforts to advance nanozyme-involved sensors for pesticides and cholinesterases.

“…Recently, nanohybrids which integrate graphene with other different types of nanomaterials such as Au, Ag, Ni, Pt, TiO 2 , ZnO, and even Fe 3 O 4 have attracted extensive attention because they exhibit not only the individual properties but also additional synergistic properties, thereby enhancing the performance in sensing applications [14][15][16]. Specifically, gold nanoparticles (AuNPs) could offer a compatible microenvironment for biomolecules immobilization without degrading their biological activity, so they have been widely introduced in biosensor and immunoassay fabrication [17][18][19][20][21]. It is thus greatly expected that AuNPs/graphene hybrids would become a novel promising candidate for application in immunochemistry.…”

Accurate diagnosis of early infections caused by the viral pathogen is a major challenge because patients usually have nonspecific signs. The development of sensitive, reliable, robust, and rapid laboratory tools is still in high demand. Herein, we developed an extremely sensitive and affordable plasmonic immunoassay for respiratory syncytial virus (RSV) detection with the naked eye based on gold nanoparticles (AuNPs)/graphene hybrids combined with metal enhancement solution. The limit of detection was found to be 1.7 fg/mL, which was 100 times higher than that of the AuNPs-based method. The ultrahigh sensitivity could be attributed to the large number of well-dispersed AuNPs deposited on the graphene surface, which had an extremely high relative surface area. Further signal amplification was achieved by catalytic enlargement of AuNPs with HAuCl 4 -NH 2 OH redox reaction. Moreover, the plasmonic immunoassay was successfully used to detect RSV in artificial serum samples, showing great potential in practical applications.
