Use only air and water to disinfect space; safe countermeasures for infectious diseases; "PeroPure", which attracts much attention, raises funds.

It is understood that PeroPure (Qingyue Technology), which developed space disinfection technology using air and water, has completed two fundraising in pre-series A. The investors are DCM and ZhenFund (town Fund) of the United States respectively, raising a total of nearly 10 million US dollars (about 1.1 billion 50 million yen). The company also received a capital injection from Stanford University TomKat Center in the seed wheel before that. Entering the era of Wizi Coronation, as carbon neutrality has become the country's medium-and long-term goal, the social demand for health and environmental protection is getting higher and higher. PeroPure grows with the development of this trend. Founder Chen Zhihua CEO received a doctorate in chemistry from Stanford University, and Associate Professor Jaramillo's laboratory specializes in the application of electrode catalytic reactors in the field of new energy. Some developing countries in Africa can only rely on large amounts of disinfectants for health management such as disinfection. The team that noticed this developed a device that could be sterilized by air and water alone and applied it to prevent flu. This is the predecessor of PeroPure. CEO Chen and several core members will launch PeroPure in the United States in 2019 to start the business of using air and water for disinfection and air purification. In early 2020, once novel coronavirus pandemic, China will pay attention to the importance of public health infrastructure, determined to put the core technology into practical application. The company's core technology "ElectroPero" is the result of eight years of research. This technology uses electrochemical oxidation-reduction method to make air react with water directly to produce hydrogen peroxide (the aqueous solution is called oxidase), which can effectively kill and decompose viruses, bacteria, organic pollutants and harmful gases on the surface or in the air. Up to now, the disinfection methods mainly use ultraviolet rays, high temperature and high pressure physical disinfection and chemical disinfection using chlorine and aldehyde disinfectants, aldehyde disinfectants, aldehyde disinfectants and so on. The disinfection technology of PeroPure not only uses air and water without residual harmful substances, but also avoids the risks caused by the transport, storage and dilution of hydrogen peroxide, which has great advantages. Usually, the chemical disinfection of the spray agent needs to be carried out in an unmanned state after the facility is open. But PeroPure's technology keeps the hydrogen peroxide produced at a safe concentration, so it can also be used in human space. After turning off the power of the disinfection device, the resulting hydrogen peroxide molecules are broken down into water and oxygen within minutes to hours, leaving no residue. Two sub-brands are being developed: "PEIDUN" for operators and "IKAAS" for ordinary consumers. Sell space disinfection devices and space disinfection robots to operators. Space disinfection devices are used in elevators or classrooms, wards, guest rooms, restaurants, buses, subways and other confined spaces. Space disinfection robots are suitable for use in airports, railway stations, shopping malls, hotels and other spacious spaces with dense flow of people. Disinfection devices for other scenarios are also under development. Consumer-oriented IKAAS is positioned as a brand of oral care and launches oral cleaners using high-pressure water spray. In the future, other oral care products will be put into use, including electric toothbrushes and professional oral cleaners. PeroPure has begun mass production. Chen CEO said that the next step will be government agencies, schools, banks, hospitals and so on, to promote the market launch of products. The company's core technology is currently testing the germicidal efficacy of novel coronavirus, and daily infectious disease prevention and control has become an important market development field. It is also expected to make active use of technology in more areas such as agriculture and environmental protection in the future. (translated by Yuko Yoshinaka)
