针对传统化学实验教学中学科前沿融入不足、实验内容综合性低等问题，本研究设计了一个综合性新创实验——基于微流控技术的镧系Eu-金属有机框架(Eu-MOFs)制备及其荧光传感研究。本实验采用前沿的微流控技术可控合成Eu-MOFs微球，结合X-射线衍射(XRD)、倒置显微技术和荧光光谱等手段系统表征其结构与性能，并探究其对Fe³⁺的荧光传感行为。结果表明，与传统方法相比，微流控法制备的Eu-MOFs具有更优的形貌均一性和更低的检测限，展现出在金属离子传感领域的良好应用潜力。本实验构建了“合成-表征-分析-实践”的全流程训练体系，引入荧光光谱仪、倒置显微镜等先进表征设备，有助于学生掌握微流控技术，深入理解配位化学与荧光传感机理。本研究为化学实验教学改革提供了新思路，对创新型人才培养具有重要实践意义。
