 | Imagine a polka-dotted postage stamp-sized sensor that can sniff out some known poisonous gases and toxins and show the results simply by changing colors. Support for the development and application of this electronic nose comes from the National Institute of Environmental Health Sciences, part of the National Institutes of Health. ...> Full Article |
 | A method for printing a toxin-detecting biosensor on paper using a FujiFilm Dimatix Materials Printer is described in the July issue of Analytical Chemistry by researchers at McMaster University and the Sentinel Bioactive Paper Network. ...> Full Article |
Ohio State University researchers have developed a new method for making extremely pure, very small metal-oxide nanoparticles. They are using this simple, fast, and low-temperature process to make materials for gas sensors that detect toxic industrial chemicals and biological warfare agents.
