【研究领域】
1.食品中痕量危害因子快速检测方法研发
以食品中痕量存在的真菌毒素/农兽药残留等典型危害因子为研究对象，针对其痕量水平、结构多样及基质干扰严重等问题，利用适配体、分子印迹等高特异性识别技术结合电化学、荧光等光电传导信号建立高灵敏、快速响应的新型检测技术，系统研究快速检测技术的传感识别机制，为建立准确、稳定、高效的快速检测方法提供理论与技术支持。
2.食品中多种危害因子智能化传感体系构建
针对食品中多类危害因子共存特性，以实际检测中多残留同步识别的需求为导向，聚焦当前传感体系在复杂食品基质中普遍存在的灵敏度低、抗干扰能力差等问题，搭建基于金属有机框架材料、上转换纳米材料等先进功能材料的新型传感检测平台，结合机器学习算法对多维传感数据进行特征提取、模式识别与智能分类，建立危害因子多残留同步检测及准确分类方法，为开展食品中危害因子污染控制研究提供技术指导。
3.可视化智能化传感技术研究
以食品添加剂（脱氢乙酸钠等）、生物标志物（挥发性盐基氮等）为研究对象，采用金属有机框架材料、钙钛矿量子点等先进功能材料建立可视化智能化传感识别体系，将传感材料集成于柔性透明基底，制备一体化、可贴附的智能膜标签，实现检测器件的微型化与便携化。进一步结合手机拍照与机器学习算法，建立基于颜色指纹图谱的智能识别模型，实现对目标物的快速定性判别与半定量分析。
