Colorimetric Plasmonic Nanosensors for Environmental Pollution Monitoring

Materials and Interfaces 2025, 2(3), 261-284

Abstract

Environmental pollution, particularly water contamination by heavy metals and organic pollutants, presents a critical global challenge requiring effective monitoring solutions. Colorimetric plasmonic nanosensors, primarily utilizing gold nanoparticles (AuNPs) due to their exceptional stability and tunable optical properties, offer a promising approach for rapid, cost-effective, and label-free pollutant detection. This review highlights recent advancements in AuNP-based colorimetric plasmonic nanosensors for environmental monitoring. We explore their fundamental sensing mechanisms and critically examine their applications in detecting a broad spectrum of waterborne contaminants, including heavy metals, inorganic species, and diverse organic pollutants. By showcasing the versatility and potential of these emerging technologies, this review emphasizes their significant contribution towards developing more efficient and accessible tools for mitigating environmental pollution and protecting public health.
