Water testing can be a cumbersome process, with labs and delays and waiting.
Chemical engineers from McMaster University have reduced the sophisticated chemistry required for testing water safety to a simple pill, by adapting technology found in...a breath strip.
Want to know if a well is contaminated? Drop a pill in a vial of water and shake it. If the color changes, there's the answer. The development has the potential to dramatically boost access to quick and affordable testing around the world.
The idea occurred to team member Sana Jahanshahi-Anbuhi, a PhD student in Chemical Engineering who came across the breath strips while shopping and realized the same material used in the dissolving strips could have broader applications.
