Rapid and sensitive on-site detection of Clothianidin in surface waters with a reusable fiber-embedded optofluidic biochip

Published: April 21, 2025

Clothianidin (CLO), a highly effective neonicotinoid insecticide, is globally utilized to combat both sucking and chewing pests. There an increasing demand for rapid high-frequency on-site detection of CLO in water food sources due its high toxicity non-target organisms. To address this, we introduce innovative decentralized testing method employing reusable fiber-embedded optofluidic biochip. This biochip leverages evanescent wave fluorescence, indirect competitive immunoassay, technology provide reliable, rapid, straightforward, cost-effective measurements. The integration all-fiber optical structure with tapered fiber nano-biosensor significantly enhances fluorescence excitation collection efficiency, bolstering the biochip's capabilities scalability. demonstrated sensitivity specificity detecting CLO, achieving satisfactory limit 1.0 µg/L within 12 min. It was successfully applied screening surface waters Beijing-Tianjin region, offering timely feedback. detected spiked recovery rates. These confirm potential as robust tool food, particularly settings limited resources. adaptable can be easily expanded detect other trace pollutants by utilizing appropriate functionalized biosensors antibodies.
