With the new technology, bacteria and viruses can be killed effectively. With the method, ordinary water is immediately transformed into an effective and environmentally friendly disinfectant as needed, writes Israel 21c.

The technology was developed by chemists at Bar-Ilan University in Ramat Gan, the technology was patented last year by the university’s BIRAD Research and Development Company.

Disinfection solutions that have previously been produced using technology have been shown to have bactericidal capabilities in hospital trials conducted in Israel.

Recently, the disinfectant also proved effective in neutralizing viruses of various Corona types in tests performed in the laboratory by Professor Ronit Sarid at BIU’s Mina and Everard Goodman at the Faculty of Life Sciences.

-We investigated the ability of the solutions to impair herpes simplex virus type 1 infection and human Coronavirus OC43. Both viruses were completely removed using the disinfectant at different times. The structural properties of OC43 are similar to those of the new SARS-CoV-2, suggesting that the virus can also be easily removed using the disinfectant, Sarid says.

Researchers Eran Avraham and Izaak Cohen developed the technology from water-to-disinfection solution in the laboratory of Professor Doron Aurbach, an international electrochemical expert at BIU’s Institute of Nanotechnology and Advanced Materials Chemistry.

method, a mixture of water and nanometer-shaped electrodes is made which has unique surface properties. The combination of these compounds creates an effective disinfectant that kills bacteria, viruses and spores.

Unlike many other disinfectants, such as chlorine, the water-based solution is safe in contact with skin and does not contaminate groundwater, the researchers say.

-The antiseptic ability is 100 times more effective than bleach and therefore low concentrations of between 50 and 200 mg of the active substances per. liters sufficient to disinfect – in contrast to bleach which requires between 5,000 and 20,000 mg per. liter. The substances are also much more environmentally friendly and do not cause burns or dry skin. They do not cause corrosion, and most importantly, with the very low concentration of 50 mg, they eliminate all kinds of viruses, the researchers say.

The technology can be used for various disinfection products such as spray aerosols for disinfection of surfaces, appliances, beds, cabinets and bathrooms, containers for immersion of hands, shoes or various devices, disinfectant wipes, air purifiers with dry mist and more.

-The ability to manufacture electrodes in different shapes and structures makes the technology suitable for almost any application – from a ‘cassette’ in an air conditioner, a container for washing fish and meat, to disinfecting and removing pesticides from vegetables and fruits , a device for making disposable antibacterial cloths and many other needs – even masks and gloves, Avraham said.

Through its startup, AqooA Solutions: Eco Sanitizing Technologies, Israeli entrepreneur Barak Dror Wanderman has worked on the final development and production of portable devices that can produce disinfection solutions as needed from drinking water.

-Imagine a situation where you are in a busy mall and want to use a public restroom. All you have to do is take out the compact spray bottle and add water – now you have a disinfectant that can be used to sterilize the toilet and toilet area and be protected, says Avraham.

The disinfectants come in special containers, they can be used for two months and sold in recyclable bottles. The recyclable bottles can be used for long-term use via a simple process, the researchers add.

-There are many different antibacterial disinfectants on the market, but this drug is water based. It is cheaper, three times as effective, seven times less toxic to humans, it retains its effectiveness much longer and can kill a wide range of bacteria, says Frances Shalit, BIRAD VP at Business Development.

-We are facing a revolution by being able to offer the population and medical institutions the most effective and green disinfectant. The technology will save many lives, save the economy a lot of money and eliminate the use of dangerous chemicals that harm the environment, says Wanderman.
