WEST LAFAYETTE, Ind. – The COVID-19 pandemic has shed new gentle on the wants for improved disinfection strategies, each for people and amenities.
Purdue College innovators have developed an airborne disinfection technique – utilizing food-coloring dyes – to be utilized to all the physique and rooms for sterilization functions and decreasing the danger of an infection.
The Purdue group’s disinfection technique makes use of edible supplies. The Purdue group offered the expertise in July throughout a COVID-19 digital convention sponsored by the Nationwide Council of Entrepreneurial Tech Switch.
“A lot of the antiviral and antibacterial sprays used for airborne antiviral and antibacterial disinfectants, equivalent to aerosolized hydrogen peroxide, ozone and deep ultraviolet illumination, are a biohazard threat to people,” stated Younger Kim, an affiliate professor of biomedical engineering at Purdue. “Moreover, disinfectants containing titanium dioxide and noble steel nanoparticles pose carcinogenic and cytotoxicity dangers.”
Kim additionally stated new strategies are wanted since transmission of pathogens (viruses and micro organism) typically happens within the air and an infection with pathogens is transmitted by an airborne route. The Purdue technique may also assist in medical settings, the place healthcare employees sometimes are uncovered to the disease-causing brokers after they take off their private protecting gear.
The Purdue airborne antiviral phototherapy method makes use of small aerosols FDA-approved meals coloring dyes to mitigate the dangers of airborne transmissions of pathogens. That is known as Photodynamic Airborne Cleaner (PAC).
“Now we have demonstrated with our novel resolution how seen gentle activation of a number of FDA-approved meals coloring dyes generate singlet oxygen, which can be utilized to kill airborne pathogens,” Kim stated. “Within the medical neighborhood, it’s well-known that singlet oxygen is efficient to inactivate viruses. We’re growing a scalable aerosol technology system for the dyes, permitting uniform fog-like dispersion lingering within the air to attenuate wetting and floor staining. As well as, as well being care employees are sometimes contaminated when eradicating PPE, this expertise may be put in in a confined chamber for well being care professionals to vary PPE in hospital settings.”
The novel photoreactive association can be utilized in rooms the place many individuals are current susceptible to airborne pathogen publicity.
The researchers are searching for companions to proceed growing their expertise. For extra info on licensing and different alternatives, contact D.H.R. Sarma of OTC at DHRSarma@prf.org and point out observe code 2020-KIM-69064.
Kim is also receiving help from Purdue’s Trask Innovation Fund, which helps labs commercialize their improvements.
