发布时间:2013-8-12  浏览次数:664

With the support of national key research project launched by Ministry of Science And Technology --- "the basic research of nanotechnology application in removing micro-pollutants from drinking water”, Institute of Intelligent Machines in Hefei has studied and developed a new mechanism based on the fluorescence detection method, and designed the corresponding detection system, which realizes the high sensitive optical detection of mercury ion selectivity in drinking water.

Drinking water safety problems increasingly attract worldwide attention. A new method and mechanism of nanotechnology to detect micro pollutants in the water---the drinking water safety assessment, is a challenging and important research work. Researchers represented by Wang Jin, Kong Lingtao in Institute of Intelligent Machines work together, using the fluorescence quenching of carbon nanomaterial graphene and fluorescence enhancement synergistic effect of gold nanoparticles, to develop a new hybrid mechanism of  "enhanced or fluorescence quenching”, which realizes the high sensitive optical detection of mercury ion selectivity in drinking water. Related papers of its achievements have been formally published in the international famous academic journals "Chemical Communication" (Chemical Communications) of British royal society (RSC). Review experts agree that this is the high integration of existing nanotechnologies, and the fluorescent detection mechanism of heavy metal pollutants in water proposed by these researchers has universality.
