At the Tokyo Olympics, the Chinese Olympic delegation not only achieved impressive results, but also 777 people returned home safely without any new crown cases, achieving the goal of “zero infection” set by the delegation before the expedition. With the domestic epidemic situation in Japan not optimistic and the number of infections increasing, the Chinese delegation can return home safely. Up to now, no one has been infected with the new crown virus. This has attracted the focus of foreign media: how did they do it?

Nikkei reported on the “light vaccine” of the Chinese team
In fact, in addition to the conventional anti-epidemic measures such as masks, disinfection equipment, and vaccines, behind the Chinese delegation there is a black technology called “light vaccine“. On August 4, Japan’s Asahi Shimbun, Nihon Keizai Shimbun and other media reported on the “off-the-board trick” used by the Chinese team: an advanced method that can achieve 99.99% sterilization against viruses and bacteria and other microorganisms, especially against the new coronavirus. Ultraviolet disinfection equipment can effectively kill in a human environment, which is a major advantage of this equipment.
222-nanometer “light vaccine“, the picture comes from the Internet
This is the 222-nanometer “light vaccine“-a “black technology” jointly developed by Columbia University, Fudan University, Shanghai Institute of Major Infectious Diseases and Biosafety, and Interstellar (Shanghai) Industrial Co., Ltd. to combat the new crown.
What is the principle of “light vaccine“? How was it developed? How does it escort the Olympic athletes? Will ordinary people have the opportunity to use it in the future? We interviewed Wu Fan, deputy dean of the Shanghai Medical College of Fudan University and dean of the Shanghai Institute of Major Infectious Diseases and Biosafety, to learn about this “black technology” of the new crown epidemic prevention.
Human and machine coexist and eliminate 99.99% of the new crown virus
The Delta Novel Coronavirus is aggressive and highly contagious. The emergence of the “light vaccine” is to protect humans by creating an environment where the virus cannot spread.
Its principle is actually very simple: “The’photovaccine’ can emit 222-nanometer wavelength radiation energy. After being highly absorbed by the new coronavirus, its ribonucleic acid (RNA) helical structure link is destroyed, causing it to lose its ability to replicate and achieve a killing effect. “In fact, all viruses, bacteria, and fungi can be killed by irradiation with a specific wavelength spectrum.
Because the short wavelength of 222 nanometers cannot penetrate the skin and eyes and is harmless to the human body, it can be disinfected when there are people. “Light vaccine” solves a difficult problem in the field of disinfection: how to achieve “human-machine coexistence, real-time disinfection”.
After the “photovaccine” device is turned on, its krypton chloride excimer tube can emit light under the excitation of high-frequency and high-voltage current. After being filtered by a nano-level high-precision optical interference membrane filter, it emits pure 222-nanometer wavelength light that is harmless to the human body. , Disinfect the exposed air and surface of objects. Killing is straightforward and nonsensical. The process does not produce any harmful substances or chemical residues.
To turn good principles, research and development into products
In 2018, Professor David Brenner of the Nuclear Medicine Research Center of the Columbia University School of Public Health found that 222-nanometer ultraviolet light is not only harmless to the human body but also highly effective for disinfection, and published a related paper in the journal Nature. This is the source of the scientific principle of “light vaccine“.
“It is necessary to turn good principles, technologies, and R&D into products and truly apply them to people’s lives.” Wu Fan said. In 2020, in the face of the domestic epidemic, the Shanghai Institute of Major Infectious Diseases and Biosafety has joined forces with Interstellar Corporation to transform the huge potential of this technology in the field of public health into actual products and technologies, and apply them quickly and effectively. New crown epidemic prevention.
In view of the cold-tolerant nature of the new coronavirus, the Shanghai Institute of Major Infectious Diseases and Biosafety led the completion of the 222-nanometer “light vaccine” at room temperature and the world‘s first cold-storage environment for the elimination of the new coronavirus. This means that at temperatures above 4°C, the “light vaccine” can cope with ease, inactivating millions of new coronaviruses in a short period of time, with an elimination rate of over 99.99%. The Shanghai Institute of Major Infectious Diseases and Biosafety also focused on the study of the relationship between the radiation dose and the elimination effect of the new crown virus. The key data generated by the experiment provided important support for future use, and how to use it in various scenarios in the future.222 Nano provides guidance.
Interstellar’s research and development team broke through one technical difficulty after another. It took only one year to launch a “light vaccine” product based on the 222 nm wavelength and applied for a series of international patents.
Zero construction and zero installation, “light vaccine” escorts Olympic athletes in this way
On the field, 99.61% of the Chinese delegation’s vaccinations and bright orange masks always protect the health of the athletes. Outside the field, more than 200 “light vaccines” are also being disinfected by humans and machines at all times to protect the Chinese representatives. The “big rear” of the regiment.
The “light vaccine” is safe and sound. During the Olympic Games, every Chinese athlete’s room in the China House and the Olympic Village for athletes’ rehabilitation and training will be equipped with “light vaccine” equipment to continuously kill pathogens in the air and environment, greatly improving biosafety . The “light vaccine” is not dazzling when used, and its disinfection factor 222 nanometers is invisible light. The human body has no perception when used, and does not affect the daily life and training of athletes.
The “light vaccine” is also convenient enough. Since the wall cannot be broken on site in Tokyo, the “light vaccine” provided to the national team is plug-and-play and equipped with customized brackets to achieve zero construction on site, zero installation, and convenient use.
The “light vaccine” is absolutely advanced. Since the “light vaccine” can “coexist with man and machine and disinfect in real time”, after repeated demonstrations by the Institute of Sports Medicine and confirmed its effectiveness against the new crown virus and its safety to the human body, it was decided to be used in the Olympic Chinese delegation. . “At present, no other company in China can achieve a high degree of purification of the spectrum to ensure the 222-nanometer disinfection that is absolutely safe for the human body.”
How far is the “light vaccine” from civilian use?The next step will be to develop anti-epidemic products suitable for more scenarios
Not only at this year’s Tokyo Olympics, but also during the anti-disaster and epidemic prevention campaign in Zhengzhou, the “light vaccine” was sent to major hospitals, and the response was enthusiastic: medical staff hoped to work within the scope of the “light vaccine” to ensure the environment Microbiological safety.
“Civilian use is a compulsory course in the future. Under the trend of normalization of epidemic prevention and control in the future, science and technology will gradually move towards civilian use and people’s livelihood. Only widespread use can reflect technical advantages.” Civilian “light vaccine” products suitable for various scenarios are also under development.
Wu Fan said: “The light with a wavelength of 222 nanometers is suitable for scenes with people. It is especially advantageous for places with higher density of people and high flow of people, as well as special places such as hospitals and nursing homes. The traditional ultraviolet light used by medical institutions is disinfected. It can only be carried out after personnel leave, but this technology can be continuously used in high-risk places such as fever clinics. In the future, it will also have broad application prospects in transportation hubs and commercial places, which can purify the environment and improve biological safety.”
However, the “light vaccine” is not a panacea. “Light does not turn. In places where there is no light, for example, if the back of an object cannot be illuminated, it cannot be disinfected. Any technology has its scope and scene.”
At present, the global new crown epidemic is far from over. “Science and technology empowers the fight against the epidemic, which is the only way to normalize the prevention and control of the epidemic.” Wu Fan said that in the next step, in addition to general products, the Shanghai Institute of Major Infectious Diseases and Biosafety and Starlight It will continue to develop products for more scenarios such as public places, airport freight, cold chain products, and monitor its disinfection effect.
Through the development and use of effective anti-epidemic products in different scenarios, the upgraded version of the “light vaccine” is expected to make greater contributions to the fight against the epidemic.
