Inspiration can come in many forms, but this one truly was a breath of fresh air. A group of McMaster researchers has solved the problem of cumbersome, expensive and painfully slow water-testing by turning the process upside-down.
Instead of shipping water to the lab, they have created a way to take the lab to the water, putting potentially life-saving technology into the hands of everyday people. The team has reduced the sophisticated chemistry required for testing water safety to a simple pill, by adapting technology found in a dissolving breath strip. Want to know if a well is contaminated? Drop a pill in a vial of water and shake vigorously. If the colour changes, there’s the answer. Read more
