Australian and German scientists have created a quantum microscope, which can be used to study previously invisible cellular structures. Technology microscopy, which writes about the publication Nature, brings science to a breakthrough in the field of biotechnology, plus, the new microscope will be useful in other areas.
The performance of light microscopy technology is limited by the random noise produced by light particles – photons. The discreteness of electromagnetic radiation quanta determines microscope parameters such as resolution, sensitivity and speed.
In an attempt to optimize microscope parameters, researchers usually increase the intensity of light by changing its sources to lasers. However, the use of laser microscopes in biology is very limited because laser light easily damages living cells. Trying to improve biological imaging, scientists from the University of Queensland and the University of Rostock went the other way – they used quantum photon correlations instead of increasing light intensity.
The authors of the new technology was able to prove experimentally that quantum correlations can improve the signal to noise ratio by 35% compared with traditional microscopy techniques, and, very importantly, eliminate the risk of damage to living cells. The new quantum microscope, as the scientists emphasize, makes it possible to see what could not be seen until now.
