Friday, 5 June 2020 | The effort to stymie the spread of COVID-19 has disinfectant and sanitizer flying off the shelves like never before. Health officials recommend sterilizing hands, work spaces and other surfaces at regular intervals, and while these guidelines are crucial, the bleach and chemicals found in disinfectant and sanitizer can often have a negative effect on our health and the environment.

Researchers at the Bar Ilan University near Tel Aviv announced that they have developed a powerful yet environmentally friendly disinfectant that targets and destroys bacteria and viruses—including the coronavirus—on all kinds of surfaces. The best part? The disinfectant is produced from normal tap water.

The water-to-disinfectant solution is the brainchild of Drs. Eran Evraham and Izaak Cohen and Prof. Doron Aurback, who heads up Bar Ilan University’s Department of Chemistry and Institute of Nanotechnology and Advanced Materials. Tests conducted at the university’s Mina and Everard Goodman Faculty of Life Sciences have already proven the solution’s ability to neutralize corona-type viruses, among others.

“We examined the ability of these materials to impair herpes simplex virus type 1 infection and human coronavirus OC43,” explained Prof. Ronit Sarid. “Both viruses were completely eliminated when exposed to the disinfectants for different periods of time.”

According to a statement released by the university, the technology entails combining nanometer-shaped electrodes bearing unique surface property with water to form an environmentally friendly antibacterial solution that destroys harmful microorganisms like viruses, bacteria and spores. Moreover, because the disinfectant is free from chlorine, bleach and other chemicals, it does not harm the skin or the environment.     

“The 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—unlike bleach, which by contrast requires between 5,000 and 20,000 mg per liter,” the Bar Ilan University scientists explained.

“They are also much more environmentally friendly and do not cause burns or dry skin. They don’t cause corrosion, and most importantly, with the very low concentration of 50 mg they eliminate all kinds of viruses.

The composition of the disinfectant makes it extremely versatile and it is suitable for use in various applications, ranging from spray-aerosols for misting and use in air-conditioning systems, sanitizing wipes, a solution for floors and surfaces to a liquid for cleaning hands and personal belongings.
