Resumen:

This chapter provides an overview of new fluorescent (bio)sensors designed for commonly used pesticides with a focus on molecular design and applications in real samples. Organophosphate and organochlorine pesticides have many applications in silviculture, public health, pest control, the food industry, and agriculture. Chronic exposure and acute contact with these agrochemicals result in toxic levels in animals, plants, humans, and ecosystems in general. Due to the toxicological, biochemical, and environmental effects of the accumulation of toxic agrochemicals in soil, food, and natural water resources, there is an imperative need to achieve analytical tools capable of working with real samples. In the last decade, research has explored the structural, reactivity, and detection aspects of sensory systems, ranging from the small organic molecules to more complex networks coordinated to metal centers involving transition metal or lanthanide ions, as well as biological nano-systems such as biosensors. The primary goal of (bio)sensors is to develop affordable, easy-to-process, efficient, economical, and stable methods for the accurate and reliable quantification of pesticides in real samples by simple visual detection. The challenge to achieve this goal starts with the (bio)synthesis strategies and their functionality in aqueous media to get efficient environmental monitoring. This chapter describes the relevant features for the development of (bio)sensors based on metal-free organic luminophores, luminescent metal-complexes, metal complexes, metal-organic frameworks, and fluorescent biosensors containing enzymes. These (bio)sensors can be used to quantitatively detect common pesticides and agrochemicals in soil, fruits, vegetables, and water. Key features include molecular strategies, luminescence detection mechanisms, scientific methodology, sensitivity, and analytical precision. © 2025 Bentham Science Publishers.
