As a trace element nutrient, cobalt is critical for both prokaryotes and eukaryotes. In the current study, a turn-on Cobalt Bioluminescent Probe 1 (CBP-1) for the detection of cobalt has been successfully developed based on oxidative C–O bond cleavage. This probe exhibited high selectivity and sensitivity toward cobalt over other analytes. By using CBP-1, the successful in vivo imaging of cobalt accumulation was carried out in a mouse model. Such an ability to determine cobalt in living animals provides a powerful technology for studying the system distribution, toxic potency, and biological effect of Co2+.
作为一种微量营养元素,钴对原核生物和真核生物都至关重要。本研究成功开发了一种基于氧化 C-O 键裂解的钴生物发光探针 1(CBP-1),用于检测钴。与其他分析物相比,该探针对钴具有高选择性和高灵敏度。通过使用 CBP-1,成功地在小鼠模型中对钴的体内积累进行了成像。这种在活体动物体内测定钴的能力为研究钴的系统分布、毒性和生物效应提供了一种强大的技术。
