“…A survey reported by China Youth Daily showed that 71.8% of Chinese people are feeling under the threat of water pollution (China Youth Daily, 2013). 190 million people fall ill and 60,000 people die from diseases caused by water pollution every year in China (Qiu, 2011;Tao and Xin, 2014).…”

Efficient detection, removal, and recovery of heavy metal ions from aqueous environments represents a technologically challenging and ecologically urgent question in the face of increasing metal-related pollution and poisoning across the globe. Although small-molecule and entrapment-based nanoparticle sensors have been extensively explored for metal detection, neither of these extant strategies satisfies the critical needs for high-performance sensors that are inexpensive, efficient, and recyclable. Here we first report the development of a regenerable fluorescent nanosensor system for the selective and sensitive detection of multiple heavy metal ions, based on light-switchable monolayer self-assembly and host-guest interactions. The system exploits photocontrolled inclusion and exclusion responses of an α-cyclodextrin (CD)-containing surface conjugated with photoisomerizable azobenzene as a supramolecular system that undergoes reversible assembly and disassembly. The metal nanosensors can be facilely fabricated and photochemically switched between three chemically distinct entities, each having an excellent capacity for selective detecting specific metal ions (namely, Cu(2+), Fe(3+), Hg(2+)) in a chemical system and in assays on actual water samples with interfering contaminants.

“…In addition to air pollution, water pollution is extending from inland to coastal areas, from surface water to groundwater, from single agent pollution to compound pollution, and from conventional pollutants to non-conventional pollutants that are surely the largest threat to the Chinese society today. Furthermore, water shortages are occurring more and more often as nearly half of the 634 Chinese rivers, lakes and reservoirs tested in 2011 failed to meet drinking standards for all or part of the year (Tao and Xin 2014). Two-thirds of China's 669 cities have water shortages, more than 40 % of its rivers are severely polluted, and 80 % of its lakes suffer from eutrophication (Liu and Yang 2012).…”

“…Wells and aquifers are contaminated with fertilizers, pesticide residues and heavy metals from the mining (Li et al 2013 and petrochemical industries as well as domestic and industrial wastes. China is short of 40 billion tons of water a year on average (Tao and Xin 2014). It is reported that about 300 million rural residents lack access to safe drinking water (Liu and Yang 2012;Dou et al 2014).…”
