Creating a safe sterilization method that can be sprayed in the air and on the body reduces infection


Researchers at Purdue University have developed a method of disinfection and sterilization that can be sprayed in the air reduces the risk of infection with the Corona virus, and the researchers used safe materials in this innovative disinfection technique, where they used edible materials that are food coloring dyes and this material can be sprayed on the body or various surfaces for sterilization purposes And reduce the risk of infection.

According to Medicall, the Corona virus pandemic has shed new light on the need to devise better and safer disinfection methods for individuals and facilities only from chemical products.

Purdue University Purification Method uses edible materials and the research team introduced this new technology in July at a virtual conference on Corona sponsored by the American Council for Technology and Entrepreneurship.

The team receives support from a fund Purdue’s Trask Innovation Fund , Which helps laboratories commercialize their innovations.

“Most of the antiviral and antibacterial sprays used in airborne antiviral and antiseptic disinfectants, such as fly hydrogen peroxide, ozone and deep ultraviolet lighting, pose a biological hazard to humans,” said Young Kim, professor at the Department of Biomedical Engineering, Purdue University.


“In addition, disinfectants containing titanium dioxide and noble metal nanoparticles pose carcinogenic risks and cellular toxicity,” he added.

Kim also said that new methods are needed because the transmission of pathogens (viruses and bacteria) occurs mostly in the air and the infection with the pathogens is transmitted through the air.

The Purdue University method may also help in medical environments, where health care professionals are usually exposed to pathogens when they take off their personal protective equipment.


Bordeaux airborne anti-light technology uses FDA food coloring dyes (FDA) To reduce the risk of airborne pathogens being referred to as a dynamic airborne light cleaner.

Kim said: “We have demonstrated with our new solution how activating the visible light of many food coloring dyes approved by the FDA generates individual oxygen, which can be used to kill airborne pathogens.”

“In the medical community, it is well known that single oxygen is effective in disrupting viruses … We are developing a system that generates aerosols that dispers and kill viruses in the air. In addition, because health care workers often get infected when removing protective equipment Personal, this technology can be installed in a room for healthcare professionals to change personal protective equipment in hospitals.
