Abstract
Persistent organic pollutants (POPs) pose significant environmental and biological risks due to their stability and bioaccumulation in the food chain, often facilitated by contamination from sewage water. Monitoring POPs is crucial for assessing their detrimental environmental impacts and preventing related health issues. Conventional analytical techniques for detecting POPs typically require labeling, energy-intensive, and cost-effective equipment, can be time-consuming, and may alter the properties of analytes. In this study, we demonstrate a label-free biosensing approach utilizing spoof surface plasmon polaritons (SSPP) for the rapid and sensitive detection of commonly encountered POPs (including textile and paper dyes, worn-out antibiotics, and herbicides) in sewage water. Inspired by plasmonic, our results show that SSPP biosensors exhibit excellent sensitivity and selectivity for POPs in sewage water samples as small as 0.634 mL. Additionally, we validate the performance of our biosensors using real-time sewage water samples spiked with widely prevalent and harmful POPs, showcasing their practical utility in complex environmental matrices. This study underscores the potential of SSPP-based biosensing as a powerful tool for the label-free detection of POPs in sewage water, offering a rapid, sensitive, and cost-effective solution for monitoring environmental pollutants. Our findings contribute to water quality assessment efforts and the development of effective pollution mitigation strategies.
