研究方向
本课题组主要致力于质谱分析方法学的研究，并以此为基础对于介观尺度下物理化学、生命科学以及合成科学的前沿问题进行研究，主要包括三个方向。
1.质谱离子化原理与质谱离子源
离子源是质谱的核心构成之一，发挥着将待测分子转化为带电离子并引入质谱的功能。我们致力于探究新颖的离子化原理和开发新型离子源以完成不同的分析任务。目前我们主要关注小体积样品（纳升至皮升级）的分析，重点发展样品损耗低的敞开式静电场诱导电喷雾方法以及电化学、光化学反应原位质谱分析方法等原位质谱分析技术。根据不同的实现原理与分析需求，通过3D打印制造零件搭建不同结构与功能的离子源装置；通过毛细管拉制仪与离子溅射装置，构筑不同分析需求中使用的纳升点喷雾载具；借助显微平台进行精细显微操作与微区分析。

2.原位质谱反应监测方法
开发原位质谱离子化方法，对于化学反应过程进行监测具有重要意义。我们利用质谱对于气液界面的反应进行研究，发现微液滴比常规化学反应体系（试管烧瓶）中反应速率更快，转化率更高。事实上，这种独特的反应加速现象不仅存在于电喷雾中，还广泛存在于液体薄膜，囊泡等小体积空间内。我们关注微液滴反应加速的深层次机理，并且关注其在分析科学中的应用。

近年来，电化学催化与光化学催化在合成科学与分析科学中引起了广泛的研究兴趣。对活性中间体的表征可以为理解电化学反应的过程与机理提供重要的实验依据。我们基于敞开式离子化的设计思路，致力于开发新颖的、原位的、准确的电化学与光化学反应界面表征方法，例如电极/电解池与质谱离子源的集成化设计、界面产物的原位采样与离子化方法等。充分借助质谱法的高灵敏度和特异性，实现对于复杂电化学过程中间体的捕获、结构鉴定与定量分析，促进全新电化学反应机理的发现与验证。

3. 超小体积生物质谱分析方法
代谢物与蛋白质是生命活动的物质与能量基础，几乎参与了机体运行的所有过程。准确获得这些物质的结构、含量、时空信息对探索生命现象和解释生命活动规律具有重要意义。我们基于采样、富集、分离、检测一体化的设计思路，致力于开发快速的、原位的、微量的、高灵敏度的代谢物和蛋白质分析方法，例如单细胞及微区活体样本的质谱原位富集与分离方法、化学选择性标记-质谱亚代谢组分析方法、临床样本中大/小分子药物在线质谱分析方法等。通过将微分离、微萃取、微电泳、化学标记等前处理技术和质谱的创新式联用，实现对于小体积复杂生物样品中代谢物、蛋白质定性、定量和定位分析，促进对生命活动、疾病诊断与治疗等机制的新发现和新理解。
