- Abstract:合成了谷胱甘肽（GSH）包覆的荧光金纳米簇（AuNCs）,基于Hg 2+ -Au + 间的高亲合作用实现对汞离子(Hg 2+ )的高灵敏性、高选择性荧光检测,线性检测范围为4～200 nmol/L,检出限（LOD,S/N=3）为2.4 nmol/L。常见的金属离子(Ni 2+ , Mn 2+ , Co 2+ , Na + , Ba 2+ , Cu 2+ , Zn 2+ , Mg 2+ , Cd 2+ , Ca 2+ , K + , Fe 3+ , Al 3+ , Pb 2+ )和阴离子（F - , C 2 O■, Cl - , H 2 PO 4 - , NO 3 - , SO■, HCOO - , I - , C 5 H 7 O 5 COO - , CH 3 COO - , Br - , CO■）对检测没有干扰。基于GSH-AuNCs构筑了两种纸型便携式AuNCs器件:半定量试纸和纸型横向流动检验（LFA）试剂盒,并成功用于可视化检测自来水样中Hg 2+ 。
