Israeli researchers develop long-lasting disinfectant to fight coronavirus

SCIENTISTS from the Technion Israel Institute of Technology in Haifa have developed “smart” disinfectants which not only destroy the coronavirus, but unlike other commonly used disinfectants that diminish rapidly, remains on surfaces for an extended period of time.

  The coronavirus has been seen to last on surfaces upwards of 17 days, and common disinfecting breaks down rapidly. This new disinfectant is long-lasting.

  “The materials we developed will be a game changer because they will block the cycle of infection from contaminated surfaces,” said Assistant Prof. Shady Farah, head of the research group.

  “Infection from touching surfaces is a serious problem, especially in public places such as hospitals, factories, schools, shopping malls and public transportation. Our polymers will make these places safer,” Farah added.

  The novel coronavirus can last on surfaces for an extended period of time, the length depending on several factors, which raises the need for a disinfectant that can also last on surfaces for long periods of time. Findings from the Diamond Princess cruise ship found that the virus can last on surfaces as long as 17 days.

  Common disinfectant methods that have been used during the pandemic rely on hypochlorite solutions, more commonly known as household bleach. These solutions both evaporate quickly, and break down when exposed to UV lights such as the sun, requiring the need for surfaces to be disinfected several times a day.
