Rapid, Sensitive and Selective Sensors for Ionic Mercury
The ability to rapidly and selectively detect and quantify chemicals has profound implications for human and environmental health. As poisonous chemicals, such as mercury (from solid-waste incineration and fossil-fuel combustion), continue to contaminate land and/or water, the development of portable, convenient “in the field” chemosensors becomes critically important. This invention provides novel colorimetric sensors for rapid, sensitive and selective detection of ionic mercury (Hg2+). The detection can be implemented using paper strip, dipstick or solution based sensors that are easy and inexpensive to manufacture and convenient to use for “in the field” measurements.
