Abstract
This research project focuses on developing a smart metal oxide nanosensor capable of rapidly detecting pesticide residues, specifically cypermethrin, on post-harvest mangoes. Using a physical vapor deposition technique, the project team synthesized highly sensitive nanomaterials measuring 50–100 nanometers and integrated them into an electronic sensing platform. These nanosensors were tested on mangoes treated with varying pesticide concentrations, producing clear and measurable changes in voltage readings that corresponded to residue levels.
The results demonstrate the nanosensor’s potential as a fast, low-cost, and field-deployable pre-screening tool that complements existing laboratory-based MRL testing. By enabling real-time detection at farms, consolidation points, and packing houses, the project offers a practical solution to improve food safety compliance and reduce post-harvest losses in the Philippine mango value chain.
