During the past two years, Chinese universities have joined in the country's scientific anti-pandemic mission, and developed efficient methods to provide strong support for containing the COVID-19 pandemic.

　　Disinfection robot

　　The intelligent disinfection robot developed by Shanghai University can replace human labor. One of these robots can spray more than 20kg of disinfectant within 15 mins. The robot can work continuously for 24 hours a day to serve key areas.

　　In the meanwhile, a robot developed by the Geely University of China can automatically create a canteen navigation map, using its laser radar and visual identity technology, so that it can complete the autonomous and continuous disinfection no matter whether the canteen is manned or unmanned.

　　Tongji NCP-AIS

　　Tongji NCP-AIS, a system developed under the leadership of Tongji University, can detect the health conditions of human bodies. Using face recognition technology and in combination with field temperature detection, this system, deployed at the front gate of Tongji University, can automatically collect and analyze the personal information of the teachers, employees and students as they enter.

　　222-nm "light vaccine"

　　Fudan University's "light vaccine" can emit pure far-UVC light with a 222-nm wavelength, having a 99.9 percent germicidal effect on the novel coronavirus. The "light vaccine" was developed to protect people by creating an environment in which the viruses cannot transmit. After the novel coronavirus absorbs a lot of such radiation energy, its RNA helical chains will be destroyed, and become unable to replicate. In this way, the virus can be killed.
