Bacteria and viruses can be killed effectively through a new method that instantly turns ordinary tap water into a powerful, environmentally friendly disinfectant on demand.<\/span><\/p>\n

The technology was developed by chemists at Bar-Ilan University in Ramat Gan and patented last year by the university\u2019s BIRAD Research and Development Company.<\/span><\/p>\n

Disinfectant solutions made with this technology previously were proven for their bacteria-killing abilities in hospital tests done in Israel.<\/span><\/p>\n

Recently, the disinfectant also proved effective in neutralizing corona-type viruses in tests conducted in the lab of Prof. Ronit Sarid of BIU\u2019s Mina and Everard Goodman Faculty of Life Sciences.<\/span><\/p>\n

\u201cWe examined the ability of these materials to impair herpes simplex virus type 1 infection and human coronavirus OC43,\u201d said Sarid.<\/span><\/p>\n

\u201cBoth viruses were completely eliminated when exposed to the disinfectants for different periods of time. The structural characteristics of OC43 are similar to those of recent SARS-CoV-2, suggesting that this virus will also be easily eliminated with this disinfectant.\u201d<\/span><\/p>\n

Researchers Eran Avraham and Izaak Cohen developed the technology for the water-to-disinfectant solution in the laboratory of Prof. Doron Aurbach, an international electrochemistry expert from BIU\u2019s Institute of Nanotechnology and Advanced Materials Chemistry.<\/span><\/p>\n

Their novel method involves mixing water with nanometer-shaped electrodes that have unique surface properties. The combination of these compounds creates an effective antibacterial against bacteria, viruses and spores.<\/span><\/p>\n

Unlike many other disinfectants, such as chlorine bleach, this water-based solution is safe for skin and does not contaminate groundwater, the researchers say.<\/span><\/p>\n

\u201cThe antiseptic capability is 100 times more effective than bleach and therefore low concentrations of between 50 and 200 milligrams of the active materials per liter are enough to disinfect \u2014 unlike bleach, which by contrast requires between 5,000 and 20,000 mg per liter,\u201d the scientists explained.<\/span><\/p>\n

\u201cThey are also much more environmentally friendly and do not cause burns or dry skin. They don\u2019t cause corrosion, and most importantly, with the very low concentration of 50 mg they eliminate all kinds of viruses.\u201d<\/span><\/p>\n

Many possible applications<\/strong><\/h4>\n

The technology could be used for a variety of disinfectant products, such as spray aerosols for disinfecting surfaces, appliances, beds, closets and bathrooms; containers for immersing hands, shoes or devices; disinfectant wipes; dry fog air-purifiers and others.<\/span><\/p>\n

\u201cThe ability to produce electrodes in a variety of shapes and textures makes the technology suitable to almost any application \u2013 from a \u2018cassette\u2019 in an air conditioner, a container for washing fish and meat, to disinfection and removal of pesticides from vegetables and fruit, a device for manufacturing disposable antibacterial cloths and many other applications \u2013 even masks and gloves,\u201d Avraham said.<\/span><\/p>\n

Through his startup, AqooA Solutions: Eco Sanitizing Technologies, Israeli entrepreneur Barak Dror Wanderman is working toward final development and production of portable devices that will produce the disinfectant liquids on demand from potable water.<\/span><\/p>\n

\u201cImagine a situation in which you are at a busy mall and are interested in using the public bathroom,\u201d says Avraham. \u201cAll you have to do is take out the compact spray bottle, access the nearest tap, and press the power button. Now you have a disinfectant that will allow you, with a simple spray, to sterilize the toilet and bathroom space and be protected.\u201d<\/span><\/p>\n

Packaged in special containers, the disinfectants can remain effective for two months and may be sold in recyclable bottles. For reusable bottled products, a fairly simple process can be applied to enable long-term use, the researchers added.<\/span><\/p>\n

\u201cThere are many antibacterial disinfectants on the market, but this material is based on water so it is cheaper, three times more effective, seven times less toxic for humans, preserves these capabilities for much longer and covers a large variety of bacteria,\u201d said BIRAD VP of Business Development Frances Shalit.<\/span><\/p>\n

\u201cWe are on the brink of a revolution by making the most effective green disinfectant available to the entire population and medical institutions,\u201d said Wanderman. \u201cThis technology will save many lives, save the economy a lot of money, and eliminate the use of hazardous chemicals that harm the environment.\u201d<\/span><\/p>\n
