Smartphone-assisted electrochemical sensors for environmental monitoring: smartphone-assisted sensors

Abstract

The rise of industrialization and urbanization has exacerbated environmental pollution, raising public concern about environmental quality. Real-time pollutant detection and rapid responses to environmental changes are crucial for safeguarding both the environment and human health. Traditional chemical analysis methods, though accurate and sensitive, are expensive, complex, and require specialized equipment and personnel. In contrast, smartphone-assisted electrochemical sensors could offer a novel, rapid, sensitive, and cost-effective solution for environmental monitoring. These sensors utilize the portability of smartphones and the high specificity of electrochemical sensors to enable real-time contaminant analysis in environmental samples. In this work, we explore the design principles, applications, challenges, and prospects of this promising technology. Despite hurdles in technology integration and data processing, smartphone-assisted electrochemical sensors are poised to become increasingly vital in environmental monitoring as technology progresses.
