According to foreign media reports, a golden ball nano headset with a diameter of 60 nm has become the most sensitive listening device in history, paving the way for the silent film dubbing of bacteria and other microorganisms

Alexander of the University of Munich in Germany and his colleagues suspended the Ginaton in a drop of water, captured a sphere from the laser beam, and then sent fast pulses from another laser device to other spheres several microns away. After the pulse hits the nanon, the nanon interferes with the surrounding water, causing pressure or sound waves

the single nano particles captured by the laser then began to shake back and forth, as if in response to sound waves. In order to prove that this shaking is not simply due to the random behavior of water molecules, the researchers changed the frequency of the sound wave. These trapped particles change with the frequency each time. And its moving direction is also aligned with the direction of great friction between the upper and lower end faces of the acoustic wave and the support of the experimental machine. This further confirms that it reacts to sound waves

Andre, a team member who also studied at the University of Munich, said: "This tiny microphone can hear a sound of minus 60 decibels at a minimum. Only one millionth of this decibel level can be detected by the human ear. That makes the nano earphone more sensitive than any listening device. We can't find any other sound detection device that can detect sound waves with such high sensitivity.

researchers from imported and domestic joint ventures can reach it. They say that this technology may enable us to listen in the future Those tiny creatures, including cells and viruses. Doing this research also gives us a better understanding of the mechanical properties of cells and how they turn into diseased cells

Yang Changhui of California Institute of technology in Pasadena, although not a team member, also supports this view. He said: "The vibration of living cells has been observed under the microscope, but no one can record their sound with a microphone. It is very interesting to study in this direction with the help of this technology.

in 2008, researchers led by Parker and Monica of the Massachusetts Institute of technology found that when red blood cells were infected with Plasmodium, their vibration decreased. It is obvious that the infection caused the cells to become stiff.

Yang He said: "this jinnazi technology may eventually enable us to detect such changes. The overflow valve, pressure reducing valve and pressure follow-up valve all adopt well-known brands. This creative technology will open up a new research field for us
