Initially, experts studied the basic mechanics of graphene, but at some point they wondered what would happen if
Collaborating with a group of nanomechanics, scientistsobserved the movement of Escherichia coli bacteria. “When a single bacterium sticks to the surface of a graphene drum, it generates random vibrations with an amplitude of only a few nanometers. They can be found. We could hear the sound of a single bacterium,” the scientists say.
Such fluctuations result frombiological processes of bacteria and the movement of their flagella (tails that push bacteria). “These flagella impacts on graphene are at least 10 billion times smaller than a boxer's impact on a punching bag. However, these nanoscale beats can be converted into audio tracks and listened to, ”the scientists explain.
This research is of great importance fordetection of antibiotic resistance. The results of the experiment were clear: if the bacteria were resistant to the antibiotic, the fluctuations simply continued at the same level, even after exposure to the drugs. But the fluctuations of those who did not show resistance first decreased and then completely disappeared. In this way, scientists could “hear” the bacteria “dying.”
