HAMILTON, ON, April 30, 2012 /CNW/ - Urban beach closures due to coliform outbreaks have become disturbing signs of summer, yet water-testing technology has never been fast enough to keep up with changing conditions, nor accessible enough to check all waters. Now, Sentinel Bioactive Paper Network funded researchers at McMaster University have developed a rapid testing method using a simple paper strip...

Urban beach closures due to coliform outbreaks have become disturbing signs of summer, yet water-testing technology has never been fast enough to keep up with changing conditions, nor accessible enough to check all waters. Now, researchers at McMaster University have developed a rapid testing method using a simple paper strip that can detect E. coli in recreational water within minutes. The new tool can close the gap between outbreak and detection, improving public safety. Scientists...

McGill researchers develop a new and inexpensive way of filtering water using silver nanoparticles Disasters such as floods, tsunamis, and earthquakes often result in the spread of diseases like gastroenteritis, giardiasis and even cholera because of an immediate shortage of clean drinking water. Now, chemistry researchers at McGill University have taken a key step towards making a cheap, portable, paper-based filter coated with silver nanoparticles to be used in these emergency settings....

Scientists in Canada are reporting the development of a fast, inexpensive "dipstick" test to identify small amounts of pesticides that may exist in foods and beverages. Their paper-strip test is more practical than conventional pesticide tests, producing results in minutes rather than hours by means of an easy-to-read color-change, they say. The study was published in ACS' Analytical Chemistry, a semi-monthly journal. John Brennan and colleagues note in the new study that conventional tests...

Canadian scientists say they've created a technology similar to inkjet printing that can be used in making paper-based biosensors to detect harmful toxins. McMaster University Associate Professor John Brennan and his research team say they've developed a method of printing a toxin-detecting biosensor on paper. The biosensor can be used to detect toxins that can cause food poisoning or that can be used as bioterrorism agents, the scientists said. The researchers said their process involves...

If that office inkjet printer has become just another fixture, it's time to take a fresh look at it. Similar technology may soon be used to develop paper-based biosensors that can detect certain harmful toxins that can cause food poisoning or be used as bioterrorism agents.In a paper published in the July issue of Analytical Chemistry, John Brennan and his research team at McMaster University, working with the Sentinel Bioactive Paper Network, describe a method for printing a toxin-detecting...
