报告摘要:
基于质谱探索新的开放环境下的电离方法以实现对呼出气化学指纹图谱的在线、快速、高灵敏分析。对呼出气进行在线质谱分析,可以解决很多关于代谢特征的有趣问题。例如:(1)是否可以在质谱“呼吸指纹”中看出个体表型的核心模式?(2)是否可以通过呼出气监测每日间的变化?(3)呼出气是否可以用于疾病诊断,如果可行,可用于哪些疾病?(4)分析呼出气的成分是否可以用来检测合理用药(或者药物滥用),是否可以用于药物代谢动力学?报告中将讲述一种大气压下基于nano-ESI的二次电喷雾电离技术(SESI)实现目标物电离的新方法,该方法可以消除将呼出气引入低压环境时对灵敏度和检测极限所产生的不利影响。这种新电离源在正离子、负离子模式下均可以工作,检测限可达到ppb-ppt量级,可检测的分子质量高达40万Da。实验中亦采用自行设计的数据处理方法对大数据集进行广泛的统计和化学计量评估。呼出气检测作为一种非侵入性的检测方式,在医疗诊断,兴奋剂检测,司法鉴定和其他领域中具有很大的潜力替代血检和尿检。
