Koronaios: “New fast and revolutionary detection test

Particularly common and practical are the ticket cancellation systems, at the gates of an airport, in the subway, inside a theater and any other public building. Built into such a common and easy-to-use machine, let us now imagine a technological device, a “detector”, which, at the time of approval of our entry into the space, also tests us for the coronavirus. Quickly, directly and mainly without the procedures we have learned in recent months. Mr. Achilleas Kapanidis, Professor of Biophysics at the Department of Physics, University of Oxford, spoke to APE-MPE about the research work that aims even at such a revolutionary technological test. participating in a research team for such a test. Mr. Kapanidis confirms that at the level of application such technology in gateways / passage of people “can be developed accordingly and help a lot”. It could, he explained, be possible in the future, so that “sampling, imaging and analysis of images (s.s. of virus particles) can be done outside the laboratory and perhaps without the participation of specialized personnel”. Challenges, as perceived by the general public and faced by the global community in relation to Covid-19 were from the outset the possibilities of diagnosis in relation to the general population. As Mr. Kapanidis explains, “Our technology, which detects the presence of the virus in clinical samples from the pharynx, is very different from the molecular method (RT-PCR) and its variants. Instead of detecting the genetic material of the coronavirus (which requires significant sample processing), we detect the virus particles directly by “staining” the virus particles rapidly (in just a few seconds) with small pieces of fluorescent DNA. We then place the particles on a surface and image them with a sensitive microscope, using an artificial intelligence program to verify that the images of the particles belong to the new coronavirus, and not to other viruses that may cause similar It points out that the whole process takes less than five minutes, uses much fewer reagents, is much simpler and more economical than the standard molecular method. The aim is to create automated detection methods for SARS – CoV 2 that can be used in high-traffic areas. This technology raises high expectations for valid and timely detection of the virus. The Greek scientist explains that first of all you will need to design a simpler microscope (or detector) for fluorescence optical microscopy (which can be produced on a large scale), and consumables for repeated sampling and microscopy. Clinical studies on the sensitivity and specificity of the test, which are currently underway, should also be completed. At the same time, as he mentioned, a company is currently being created, with the help of the university, to promote these developments as soon as possible. “In the medium term we believe that these developments will lead to tests, which will be very economical and available to the wider community,” said Mr. Kapanidis. The professor of Biophysics at the Department of Physics at the University of Oxford points out that this technology is based on logic that “sampling, imaging and analysis of images can be done outside the laboratory in the future, and perhaps without the participation of specialized personnel”. “We have also started contacts with a large airport for this very reason. Other venues include large corporations and theaters, “he said, referring to the design for the future. from a few days) to identify other viruses that may cause similar symptoms, and have a lipid envelope, such as the flu virus. In fact, our contribution in this field began with research and detection of various types of influenza virus, which of course are dangerous for the pandemic “, concludes the professor of the University of Oxford. Greek scientists work together to get out of the pandemic quickly. notes that Greek scientists, like all scientists in the world, work hard, innovate hopefully under difficult conditions and work together in new ways so that the human community has many choices on many levels (vaccine, treatment, diagnosis, information, etc.), so to get out of this alley as soon as possible “while welcoming the national effort of Greece.” As Greeks abroad, we are happy and proud that the Greek society with the help of its scientists effectively faced the first wave of the coronavirus SARS-CoV- 2, and we hope that it will stop the second wave despite the difficulties “, he points out. However, he warns that “as has been shown in recent years, our modern way of life unfortunately leads to the certainty that dangerous microorganisms (such as many new viruses and bacteria resistant to existing antibiotics) will be with us immediately and for many years”, so ” we will definitely need a new generation of scientists, not only in the field of microbiology but also in all the sciences that can help in understanding the mechanisms of microorganisms and in the ways of their control and analysis “. In fact, he cites as an example of contribution from the natural sciences, the contribution to the work of his team by Nikolas Siaelis, an excellent doctoral researcher from Cyprus, who is the main person responsible for research and innovation that is the basis of this new test.
