They record the sound of a bacterium and the result is surprising

how the sound bacteria? This question seems almost as difficult to answer as “what do clouds smell like”. However, after the publication of a new study in Nature’s nanotechnology, it is much easier to give you an answer. And it is that a team of scientists from Technical University of Delft managed to record the sound of a bacteria when placed on a drum of graphene.

Beyond the curious results, it is a very useful study, because it can be used to detect antibiotic resistance in a simple way and above all, quick. When a person’s life is at stake due to a serious infection, it is vital to determine the best treatment as soon as possible. If you decide to use an antibiotic to which the bacteria in question is resistant, you are wasting valuable time.

This is why this study is so useful, because detecting resistance would be as simple as checking if the bacteria noise it stops when they come into contact with the antibiotic in question. If it stops, it is sensitive and can be a good treatment. If you continue your song It’s time to keep trying and cross your fingers that there are still options that can end the infection.

Serendipity studies graphene

In fact, the authors of the just-published study didn’t begin their research with that in mind. They were just studying properties of graphenea material that has had very bad press during the pandemic, but which has an immense range of possibilities.

It is made up of carbon atoms, arranged in a regular hexagonal pattern. He is very resistant. In fact, a sheet just one atom thick is 200 times stronger than steel. But it is also lighter, precisely about 5 times lighter than aluminum. In addition, it conducts heat and electricity very well and can be dope, adding impurities from other substances that give it new properties. All this already makes it a great material, But there is even more. For example, it has been proven to be able to self-repair.

Graphene is extremely sensitive to external forces, so they thought they could measure its vibrations when it comes into contact with bacteria.

Logically, thanks to these properties, graphene is a highly valued material in areas such as electronics, space engineering or biomedicine. Although no, vaccines don’t contain graphene and neither do masks, let’s be clear.

These scientists were particularly interested in their medical applications. Therefore, they wondered what would happen if he interacted with a single biological object, like bacteria. It is known to be extremely sensitive to external forces, so the movement of the bacterial flagella could cause vibrations detectable with appropriate sensors.
