摘要

在临床诊断和食品质量评估中，L-乳酸盐是一种重要的生物标志物。本研究介绍了一种新型比率荧光传感器 RhB@Zn-MOF，该传感器专门设计用于灵敏、选择性地检测 L-乳酸盐。通过在 Zn-MOF 中策略性地加入罗丹明 B (RhB)，合成了 RhB@Zn-MOF，该传感器具有双发射特性，基于竞争性吸收机制，可有效区分牛奶和汗液等复杂生物和食品基质中的 L-乳酸盐。值得注意的是，该传感器实现了 0.091 μM 的低检测限，并在不同条件下表现出优异的稳定性和重现性。此外，该传感器与智能手机技术的整合实现了快速、实时的分析，展示了在运动医学、临床环境和食品工业中的潜在应用。

Highly sensitive and selective L-lactate monitoring in complex matrices with a ratiometric fluorescent sensor RhB@Zn-MOF

L-lactate is an essential biomarker in clinical diagnostics and food quality assessment. This study introduces a novel ratiometric fluorescence sensor, RhB@Zn-MOF, which was specifically designed for the sensitive and selective detection of L-lactate. Through the strategic incorporation of Rhodamine B (RhB) into Zn-MOF, RhB@Zn-MOF was synthesized, exhibiting dual-emission properties and could effectively distinguish L-lactate in complex biological and food matrices such as milk and sweat based on the competitive absorption mechanism. Notably, the sensor achieves a low detection limit of 0.091 μM and demonstrates excellent stability and reproducibility in varied conditions. Furthermore, the integration of the sensor with smartphone technology enables rapid, real-time analysis, showcasing potential applications in sports medicine, clinical environments, and the food industry.
