In-field deployable and facile nanosensor for the detection of pesticides residues

Local air and water should be first priority to understand the environment of any area. Different categories of contaminants behave like bottleneck situation in collection and analysis of data about abiotic factors for the understanding and resolving the environmental issues. In digital age the emerging nano technology enroll its role to meet the needs of hour. Due to increase in pesticides residues, the global health threats are on bloom because it inhibits the functionality of acetylcholinesterase (AChE) enzyme. Smart nanotechnology based system can tackle this issue and sense the pesticides residues in environment and vegetables as well. Here Au@ZnWO4 composite is reported, for accurate detection of pesticides residues in biological food and environmental samples. The fabricated unique nanocomposite was characterized by SEM, FTIR, XRD and EDX. The characterized material used for the electrochemical detection of organophosphate pesticide (chlorpyrifos), with 1 pM LoD at a signal to noise ratio of 3. The main concern of study is to help out in disease prevention, food safety and ecosystem protection.

Automated summary

Understanding the local air and water is crucial for assessing the environment of any area. Different types of contaminants present challenges in collecting and analyzing data about abiotic factors that contribute to environmental issues. Nanotechnology has emerged as a solution to address the increase in pesticide residues, which pose risks to global health. A smart nanotechnology-based system, using the Au@ZnWO4 composite, has been developed for accurate detection of pesticide residues in biological food and environmental samples. The study aims to contribute to disease prevention, food safety, and ecosystem protection.
