	1	Simultaneous Fluorescence Detection of Mercury(Ⅱ) and Silver Ions Based on Rhodamine B Isothiocyanate and 5-Carboxyfluorescein-ss DNA Modified Probe显示文摘A new fluorescence sensor is developed for simultaneous detection of Hg^(2+) and Ag^+. During the detection process,Hg^(2+) forms complexes with the fluorescent dye rhodamine B isothiocyanate(RBITC) modified onto the surface of gold nanoparticles(Au NPs),resulting in RBITC's displacement from the surface of Au NPs and the recovery of fluorescence. Meanwhile,Ag^+ forms 'C-Ag^+-C' complex with C-rich 5-carboxyfluorescein(FAM)-ss DNA modified onto the surface of Au NPs,which keeps the fluorescent dye FAM close to the Au NPs and results in quench of fluorescence. The experimental results show a wide linear range and a good sensitivity. The limit of detection is 1.06 nmol/L for Ag^+ and 0.48 nmol/L for Hg^(2+). This detection method is not only easy to operate but also efficient.	CHEN Yinran MAO Kang ZHOU Xiaodong SHEN Aiguo HU Jiming	2016	Wuhan University Journal of Natural Sciences2016，21，6：	0
