报告题目:活体质谱与成像
报 告 人:聂宗秀 研究员(中国科学院化学研究所
报告时间:2018年5月29日  9:30
报告地点:武汉大学化学与分子科学学院创隆厅
个人简介:
1973年5月生。2003年获中国科学院武汉物理与数学研究所博士学位。2005-2008年分别在台湾中央研究院原子分子科学研究所和美国普渡大学化学系博士后。2009年1月入选中科院“百人计划”计划,任中科院化学所研究员。2016年获国家基金委“杰青”。独立工作以来,发表通讯作者论文49篇,其中包括1篇Nature Nanotech.、14篇Anal. Chem.、2篇Chem. Eur. J.、2篇Chem. Commu.。发表在Nature Nanotech.上的工作,由杂志社撰文在同期的“新闻视角”中进行了专栏评论,被Chem. Res. Toxicol.选为“研究亮点”,入选2016年Nature Nanotech.杂志10周年专刊。授权中国发明专利18项。


基质辅助激光解吸电离(MALDI)质谱成为蛋白质组学、基因组学、代谢组学、醣体学、脂质组学,以及质谱成像等研究中不可或缺的工具。然而,由于传统基质在小分子区域的严重背景干扰,阻碍了MALDI对小分子化合物(m/z < 1000)的质谱分析。近年来,我们一直致力于新型无背景干扰基质的研究,用于复杂生物体系中小分子化合物的质谱分析与成像,开发出了系列高耐盐性,低背景干扰的有机盐新基质。结合大鼠中动脉栓塞、结肠癌肝转移和肾纤维化等生理模型,实现了生物组织切片的质谱成像,原位检测了组织中非脂质小分子化合物和甘油磷脂的代谢变化和空间分布。此外,基于碳纳米材料低分子量区域的特征指纹质谱方法,获得了碳纳米管,碳纳米点,氧化石墨烯等碳纳米材料在生物组织以及组织亚器官中的分布,同时对其进行了定量质谱成像研究。研究发现,碳纳米管和碳纳米点主要分布于肾组织的外实质部分,所有材料在脾脏的红髓均有分布,碳纳米管在脾脏组织中的边缘区域浓度最高。
