Abstract
Pesticide residues present a notable risk to public health, making it essential to develop swift and dependable analytical techniques for ensuring food safety. Here, three novel high-entropy metal-organic frameworks with peroxidase-mimetic activity were synthesized. Leveraging their differential catalytic responses to various pesticides, a three-channel sensor was constructed for discrimination of five organophosphorus pesticides (glyphosate, chlorpyrifos, trichlorfon, diazinon, dichlorvos), achieving a detection limit of 0.50 μg mL-1. The sensor operates effectively across a broad concentration range (0.50-50 μg mL-1) and successfully identifies complex mixtures, including structural analogs like glyphosate and chlorpyrifos. With excellent interference resistance and practical applicability in real samples, this strategy offers a simple and effective method for multi-pesticide identification, showing great promise for advancing food safety monitoring.
Organophosphate pesticides are extensively used in agriculture, but their improper use and persistence in the environment can pose significant risks to human health and ecological safety. Rapid, simple, and cost-effective methods for detecting organophosphate contamination are essential, particularly in resource-limite...

The continuous discharge of heavy metal ions resulting from intense industrial activity into the environment poses risks to all life on Earth (high toxicity and bioaccumulation). As a consequence, it is critical to develop analytical methods and sensors capable of detecting traces of heavy metals in a fast, accurate, a...

Organophosphorus pesticides (OPs) pose significant environmental and health risks due to their persistence and neurotoxicity, yet current detection methods rely on sophisticated instrumentation inaccessible to educational settings. To address this pedagogical gap, we developed a recyclable Au-R-Fe3O4 nanozyme cascade...
