Experts say this study is of great importance in determining resistance to antibiotics.
The team of scientist Farbod Alijani at Delft University of Technology captured the noise the bacteria makes while initially investigating the underlying physical mechanics of graphene. Scitech Daily writes about it.
It was noted that graphene is a form of carbon composed of a single layer of atoms, also known as a miracle material.
“It’s very durable, with excellent electrical and mechanical properties, and also very sensitive to external forces. This animation shows how a graphene drum can reproduce the sounds of bacteria. The sound stops when the bacteria is destroyed by an antibiotic, “the scientist noted.
When a single bacterium sticks to the surface of a graphene drum, it generates random vibrations with an amplitude of only a few nanometers that can be seen, he says.
“We hear the sound of a bacterium! To understand how small these flagellum blows in graphene, it’s worth saying that they’re at least 10 billion times smaller than a boxer’s blow in a punching bag. However, these nanoscale bits can be converted into soundtracks and listen – and how beautiful it is, “Alijani added.
Scientists say this study is of great importance in determining resistance to antibiotics. At the same time, the results of the experiment were not ambiguous: if the bacteria were resistant to the antibiotic, the changes continued only at the same level. When the bacteria are susceptible to the drug, the volatility subsides in an hour or two, but then they completely disappear. Due to the high sensitivity of graphene drums, this phenomenon can be determined using only one cell.
“In the future, we aim to optimize our single-cell graphene antibiotic susceptibility platform and test it on different pathogenic samples. So eventually it will be available as an effective diagnostic tool to quickly determine antibiotic resistance in clinical practice ,” the studying. added the leader.
Remember that biologists have discovered a strain of bacteria that eats vitriol and produces pure copper.
