Better Water Testing, Thanks To Breath-Freshening Strips
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.
The development has the potential to dramatically boost access to quick and affordable testing around the world.
