In this work, a new magnetic, ratiometric fluorescent nanoprobe has been designed and fabricated by encapsulating FeO magnetic nanoparticles (MNPs) and dual-emissive carbon dots into the cavities of metal-organic frameworks (MOFs). This one-pot method combined hybrid characteristics of MOFs with multiple properties of the encapsulated functional materials. The MOF-based nanoprobe possessed the advantages of MOFs (strong adsorption ability, accumulating the analytes), FeO MNPs (magnetic separation), and ratiometric sensors (eliminating the variabilities caused by the instability of the instruments and environment). The MOF-based nanoprobe was dispersible and stable in aqueous solution, and the nanoprobe was applied to HClO sensing. This work will provide a promising strategy for design and synthesis of novel MOF-based composite materials.
在这项工作中，通过将 FeO 磁性纳米颗粒（MNPs）和双发射碳点封装到金属-有机骨架（MOFs）的腔体内，设计并制备了一种新型的磁性、比率荧光纳米探针。这种一锅法将 MOFs 的混合特性与封装功能材料的多种特性相结合。基于 MOF 的纳米探针具有 MOFs（强吸附能力，积累分析物）、FeO MNPs（磁性分离）和比率传感器（消除仪器和环境不稳定引起的可变性）的优点。基于 MOF 的纳米探针在水溶液中具有良好的分散性和稳定性，并将纳米探针应用于 HClO 传感。这项工作将为设计和合成新型基于 MOF 的复合材料提供一种有前途的策略。
