Monitoring of pesticide focus distribution throughout farm fields is essential to make sure exact and environment friendly software whereas stopping overuse or untreated areas. Impressed by nature’s wettability patterns, we developed a biomimetic fern leaf pesticide assortment patch utilizing laser-induced graphene (LIG) alongside an exterior electrochemical LIG biosensor. This “collect-and-sense” system permits for fast pesticide spray monitoring within the farm subject. The LIG is synthesized and patterned on polyimide by means of a high-throughput gantry-based CO2 laser course of, making it amenable to scalable manufacturing. The ensuing LIG-based leaf reveals a exceptional water assortment capability, harvesting spray mist / fog at a price roughly 11 instances higher than a pure ostrich leaf when the gathering is normalized to the floor space. The developed three-electrode LIG pesticide biosensor, that includes a working electrode functionalized with electrodeposited platinum nanoparticles (PtNPs) and the enzyme glycine oxidase, displayed a linear vary of 10-260 µM, a detection restrict of 1.15 µM, and a sensitivity of 5.64 nA µM-1 for the broadly used herbicide glyphosate. Additionally, a conveyable potentiostat with a user-friendly interface was developed for distant operation, reaching an accuracy of as much as 97%, when in comparison with a regular industrial benchtop potentiostat. The LIG “collect-and-sense” system can constantly accumulate and monitor glyphosate spray after 24-48 hours of spraying, a time that corresponds to the restricted-entry interval required to enter most farm fields after pesticide spraying. Therefore, this progressive “collect-and-sense” system not solely advances precision agriculture by enabling monitoring and mapping of pesticide distribution but additionally holds the potential to considerably scale back environmental affect, improve crop administration practices, and contribute to the sustainable and environment friendly use of agrochemicals in trendy agriculture.
