摘要

Innovative approaches are necessary for the efficient monitoring and restoration of environmental contamination, as it poses significant threats to human health and ecosystems. By utilizing the distinct characteristics of nanomaterials, nano sensors present encouraging developments in the identification and reduction of environmental contaminants. This review article offers a thorough investigation of the function of nanosensors for environmental remediation and monitoring. Nanomaterials, fundamental to the functionality of nanosensors, are explored in depth, with a focus on characterization techniques, green nanoparticles, and metal nanoparticles. The properties and applications of these nanomaterials in enhancing nanosensor performance are detailed. Sensing techniques and mechanisms, including selectivity and sensitivity enhancement strategies, are critically analyzed to demonstrate the efficacy of nanosensors in various environmental contexts. The several forms of pollution (soil, water, and air) and the environmental problems they cause are outlined, highlighting the need for accurate remediation techniques and detection systems. Within the scope of the review, pathogens, heavy metals, hazardous pollutants, pesticides, fertilizers, and air pollutants are all identified and monitored. Focus is placed on the use of carbon nanosensors for air quality monitoring and the application of nano-biosensors in precision agriculture. Several real-world uses for nanosensors are shown, demonstrating how they might enhance environmental health. This review acknowledges the benefits of nanosensors, including their high sensitivity and real-time monitoring, but it also discusses their drawbacks and difficulties, like their manufacturing costs and possible environmental effects. Furthermore, this review discusses the future prospects of nanosensors, emphasizing the potential for continued innovation and interdisciplinary collaboration to enhance environmental monitoring and remediation efforts. The revolutionary potential of nano sensors in protecting natural resources and guaranteeing a sustainable future is reaffirmed in the conclusion.
