Manual DNA computer that detects water pollution

There are many filters around the world that identify polluted water but now a very interesting water sensor based on real DNA have been created but it expresses pollution in computer language.

Julius Lux of Northwestern University in Illinois has developed a bio-computer sensor that works from DNA, which is very low cost and simple. On the one hand, it is a simple sensor that shows water pollution, on the other hand, it will also advance the development of biological computers.

Just one drop of water can detect this contamination. It contains the DNA of a modified protein that emits light molecules in the presence of contaminated alchemy components. In this way, one can only guess how dirty the water sample is.

An unsuccessful attempt was made to add live bacteria to the first filter. But even its engineering did not help because it was very difficult to keep the bacteria active. This was followed by a study of synthetic (synthetic) organisms.

Now, this state-of-the-art sensor computer provides excellent results thanks to modified DNA and can detect dangerous chemicals in the water. Named the Rosalind Two, it is equipped with eight small test tubes, each of which is equipped with sensors measuring different levels of pollution.

Now if a tube lights up, it indicates that there is a contamination in it. If more tube lights are emitted, they indicate that the water is slightly contaminated.

Modified DNA fibers stick to each contaminant and emit light. In this way, each tube indicates the severity of the contamination. In this way, the intensity of the contamination can be ascertained by looking at the light in the tube.

When tested, DNA sensors successfully detected zinc in water, antibiotics, and many chemicals released from industrial waste.

The solution of this sensor can be frozen and sent from one place to another. Now it can be prepared by adding a few drops of water.

According to Dr. Julius, the sensor is specifically designed to test drinking water. On the other hand, it is very low cost and easy to use.
