Accurate biodetection of trace uranium by electrochemiluminescence and its application inIn vivo toxicokinetic dynamic research

Bioinspired FeN5 Sites with Enhanced Peroxidase-like Activity Enable Colorimetric Sensing of Uranyl Ions in Seawater

“…As the main form of uranium, UO 2 2+ is distributed in the Earth’s crust and oceans. , Due to the continuous escalation of human activities, such as nuclear testing, nuclear accidents, and the discharge of wastewater from nuclear power plants, uranium’s profound chemical and radiological toxicity poses an increased risk to human health. , Therefore, it is necessary to develop a sensing platform with high sensitivity and accuracy to realize UO 2 2+ detection (Figure a). Accordingly, based on the unique structure and electronic properties of actinide U, the hybridization of 5d-6f orbital results in the linear structure of UO 2 2+ (OUO) 2+ . ,, The presence of the single electron on the N of the imine (–NH) in the oxTMB can form the complex with UO 2 2+ ions. , In detail, the binding energy peak of U 4f of the complex is observed in the XPS spectrum (Figure b).…”
