Rapid and Convenient Detection: The paper strip or dipstick based sensors allow for rapid, convenient and easy detection of Hg2+. The colorimetric responses are instantaneous.
About
Technology 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. Applications • Rapid Colorimetric Sensors for Agricultural and Environmental Applications: Portable, convenient and instantaneous "in the field” colorimetric detection of Hg2+ using paper strips, dip sticks or colorimetric solutions; ultrasensitive colorimetric detection of these chemicals using a spectrophotometer. • Rapid Sensors for Chemical Impurities and Contaminants: “In the field,” laboratory or Industrial detection and quantification of Hg2+ as chemical impurities and contaminants.
