Exercise-induced muscle injury is one of the most common types of sports injuries. Skeletal muscle troponin I (skTnI) serves as an ideal biomarker in assessing such injuries, facilitating timely detection and evaluation. In this study, we develop a fluorescent sandwich lateral flow immunoassay (LFIA) combined with a desktop analyzer for rapid detection of skTnI. Through optimizing the reaction system, the assay achieves a satisfying detection performance, reaching a limit of detection (LOD) of 0.5 ng/mL with a turnaround time of 15 min. The proposed detection platform offers portability, ease of use, and high sensitivity, which facilitates the monitoring of exercise-induced muscle injuries at the point of care. This feature is particularly advantageous for end users, enabling timely detection of sports-related injuries and ultimately enhancing prognosis and sports life.
运动性肌肉损伤是最常见的运动损伤类型之一。骨骼肌肌钙蛋白 I（skTnI）作为评估此类损伤的理想生物标志物，有助于及时进行检测和评估。在这项研究中，我们开发了一种荧光三明治侧向流动免疫分析（LFIA），结合台式分析仪，用于快速检测 skTnI。通过优化反应体系，该分析方法实现了令人满意的检测性能，检测限（LOD）为 0.5ng/mL，检测时间为 15 分钟。该检测平台具有便携性、易用性和高灵敏度，有助于在护理点监测运动性肌肉损伤。对于终端用户来说，这一特点尤其有利，能够及时发现与运动相关的损伤，从而改善预后和运动寿命。
