A new test in a few minutes and with just a drop of water will determine its safety

The new test was led by researchers from Northwestern University. He can

detect 17 different contaminants, including toxic metals such as lead and copper, pharmaceuticals, cosmetics and cleaning products.

The main problem of ensuring water qualityis that people cannot find out about the presence of contaminants in liquids, and sending a sample for examination can cost up to 10 thousand rubles. 

The researchers used cell-freesynthetic biology: They take molecular machinery, including DNA, RNA and proteins, out of cells and then reprogram that machinery to perform new tasks. It's like opening the hood of a car and removing the engine, which you can now use for various purposes. 

The platform, based on cell-free synthetic biology, is so flexible that researchers can constantly update it to identify more and more different pollutants.
