Paper tape detects E. coli

To test Escherichia coli in drinking water or food, samples should be sent to laboratories, usually for a long time and cost effective.

Plate of E. coli

Now, researchers at McMaster University in Canada have developed a paper tape capable of detecting E.Coli in just 30 minutes.

This tape is not only lightweight, simple to use, but also easy to produce and cheap. Scientists use inkjet technology to coat the color indicator onto the surface of the paper. When the paper is immersed in water, if it is contaminated with E. coli, the color on the paper tape changes, depending on the level of pollution.

Funded by the Canadian National Council of Scientific Research, a team at McMaster University led by chemistry professor John Brennan is continuing the development of the next phase of research and commercialization. with expected completion in the next 2 years.
