Most organophosphorus pesticide (OP) sensors reported in the literature rely on the
inhibition effect of OPs on the activity of acetylcholinesterase (AChE), which suffer from the …

In 2007, landmark research recognized ferromagnetic nanoparticles (Fe3O4 NPs) as the
substitute of horseradish peroxidase (HRP) for their alike catalytic ability to oxidize signal …

Traditional peroxidase-like nanozyme-based sensors suffer from self-decomposition and
high toxicity of H2O2, as well as the interference of color from nanozymes themselves and …

Common homogeneous electrochemical (HEC) sensors usually suffer from the drawbacks
of high background signal, low signal-to-noise ratio, and even false positive results due to …

Nanozyme-based colorimetric assays have shown great potential in the rapid and sensitive
determination of pesticide residue in environment. However, the non-specific enzyme …

Metal‐free carbon nanozymes could be promising with the unique features of intrinsic
catalytic ability, structure diversity, and strong tolerance to acidic/alkaline media. However, to …

Developing portable, quantitative, and user-friendly analytical tools for sensitive pesticide
