Repeated and unregulated use of pesticides on agricultural land wreaks havoc on the environment, threatening and weakening the biodiversity and ecosystem. It is a growing concern for global stability and the sustainability of the environment. The detection of pesticides in the soil at lower concentrations remains a challenge today. In the current decade, nanotechnology is the emerging technology that helps in promoting a sustainable and reliable approach in the agricultural sector. The pesticide residue analysis is an urgent call to safeguard soil quality, reduce health issues, and protect the ecosystem by the excessive use of pesticides. The use of sensor technology for pesticide detection is considered a promising alternative strategy compared to traditional chromatographic detection techniques. Nanosensors possess excellent sensitivity, can detect even low concentrations, and are more stable and reliable for smart agriculture. Developments of nanosensors and nanobiosensors continue to serve a crucial role in the upgradation of the agriculture sector. In this chapter, we have covered various types of nanosensors and nanobiosensors used for pesticide residue analysis in soil.

Keywords: Chromatography techniques, pesticide detection, electrochemical nanosensors, optical nanosensors, enzyme-based nanobiosensors, immunonanosensorsna, noaptasensors, soil.
