To combat the new coronavirus, researchers at Ben Gurion University in Israel have recently developed a new coating that contains metal ions and polymer nanoparticles with antiviral and bactericidal activity.
Professor Angel Porgador of the University's Department of Microbiology, Immunology and Genetic Engineering, Professor Mark Schvartzman of the Department of Materials Engineering and PhD students Yariv Greenshpan and Esti Toledo participated in the above-mentioned research projects to analyze the effects of various metal nanoparticles on coating antiviral properties.
that the introduction of a certain dose of metals that are not toxic to humans can be fatal to viruses and bacteria
. For example, the coating surface of copper nanoparticles can effectively inhibit the infectiousness of viral cells.the antiviral coating developed by
can be painted or sprayed on the surface of the substrate, and the polymer-coated nanoparticles can control the release of metal ions on the coating surface, which have strong antiviral properties and eliminate the virus attached to the substrate surface. Because ion release is very slow, antiviral effectiveness can last for weeks or even months, which greatly reduces the spread of the virus.
, CEO of a technology transformation company owned by Ben Gurion University, said, "As the new global crown epidemic spreads, there is a surge in demand for antiviral coating research and development." Even after the outbreak, the need for this coating is high due to increased awareness of health risks. This coating product will play an effective role as a universal antiviral sterilization coating, not only for hospital medical equipment, but also for other places such as schools, airports, public transport, cinemas and so on. In fact, the academic community is conducting a widely participated, interdisciplinary research to find effective solutions to the current medical and economic difficulties. The
