A colorimetric/fluorescent dual-mode sensor for ultra-sensitive detection of Hg2+

A novel colorimetric/fluorescent dual-mode sensor is presented for the detection of Hg2+. The proposed strategy showed good selectivity to Hg2+ and the simultaneously colorimetric/fluorescent detection platform hold advantages of both easy observation and high sensitivity in salt solution with a broad range of concentration, which had good potential for environmental analysis.128
