"Light Vaccine": Black Technology to Protect the National Olympics Corps' New Crown Zero Infection

At the Tokyo Olympics, the Chinese Olympic delegation not only achieved an impressive record, but since returning to China, no one has been infected with the new crown virus so far

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": a kind of anti-virus and bacteria and other microorganisms, especially against the new coronavirus, can achieve 99.

This is the 222-nanometer "light vaccine"-a "black technology" developed by Columbia University, Fudan University, Shanghai Institute of Major Infectious Diseases and Biosafety, and Interstellar Light (Shanghai) Industrial Co.

What is the principle of "light vaccine"? How does it escort the Olympic athletes? Do ordinary people have the opportunity to use it?

The reporter recently interviewed Wu Fan, the deputy dean of Shanghai Medical College of Fudan University and the dean of the Shanghai Institute of Major Infectious Diseases and Biosafety

Human and machine coexist to effectively kill the new crown virus

Its principle is actually very simple: the "light vaccine" protects humans by creating an environment where the virus cannot spread

"The'photovaccine' can emit 222-nanometer wavelength radiation energy.

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

According to reports, after the "light vaccine" equipment is turned on, its krypton chloride excimer tube can emit light under high-frequency and high-voltage current excitation.

To turn good principles, research and development into products

A 2018 study by Professor David Brenner from 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.

"It is necessary to turn good principles, technologies, and R&D into products and truly apply them to people's lives

In 2020, in the face of the domestic epidemic, the Shanghai Institute of Major Infectious Diseases and Biosafety and Interstellar will jointly transform the huge potential of this technology in the field of public health into actual products and technologies, and apply them quickly and effectively.

In response to the cold-tolerant nature of the new coronavirus, the Shanghai Institute of Major Infectious Diseases and Biosafety has led the completion of the 222-nanometer "photovaccine" at room temperature and the world's first cold-storage environment for the new coronavirus elimination experiment-which means that the temperature above 4 ℃ The "light vaccine" can cope with temperature freely, inactivating millions of new coronaviruses in a short time, with an elimination rate of over 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.

It took only one year for the research and development team of Interstellar Light to launch a "light vaccine" product based on a wavelength of 222 nanometers

How far is the "light vaccine" from civilian use?

Except for the Tokyo Olympics, the "light vaccine" has been sent to major hospitals in Zhengzhou's anti-disaster and epidemic prevention war

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 can especially show its advantages in places with high density of people and large flow of people, as well as in special places such as hospitals and nursing homes .
The traditional ultraviolet light used by medical institutions must be 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
.
" Wu Fan said
.

"Science and technology empowers the anti-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 Interstellar will continue to develop research and development for public places, Airport cargo and other products used in more scenarios, and monitor its disinfection effect
