Some recent studies have shown that copper can effectively inhibit the spread of new coronavirus. As the world’s largest copper producer, Chile is currently a leader in global antibacterial material production.
According to the Santiago report from April 23, before the arrival of the new coronavirus, Chile, which accounted for 28% of global copper production, had taken the lead in using this red metal as a means of combating fungi, bacteria and viruses.
According to reports, more than ten years ago, thanks to public investment, the Chilean National Copper Company promoted the development of a technology that adds copper particles to objects to convert their surfaces or materials into antibacterial agents.
Copptech, which develops this technology, is currently exporting it to the United States and some Asian and European countries, involving medical supplies, textiles, and plastic paint surfaces and coatings.
The CEO of the company, Francisco Silberberg, explained to reporters, “By applying varnish containing copper to public transportation, airports, hospitals, schools and other infrastructure, you can fight the spread of the new coronavirus. These facilities The antibacterial and antiviral properties can be maintained for ten years. “
Humberto Parsa, Ph.D. in Materials Science at the University of Chile agrees: “This will effectively combat the new coronavirus, because airborne transmission is the most powerful method of transmission. Its concept is to allow the surface of the object itself to kill viruses without Rely on disinfection to reduce infection. “
It is reported that other companies using this technology have also joined the fight against the new coronary pneumonia: the startup Copper 3D gave a 3D printed design with a copper particle mask. The “Tackling the Pandemic” campaign it launched to promote the global printing of its models received a positive response, and the design drawings were downloaded more than 5 million times.
Parsa, who has promoted a number of researches on copper, told reporters that Chile was the first country to conduct research on this metal as an antibacterial material, and related industries have developed tremendously in the past 25 years.
He said: “Chile is working with many relevant departments to promote development. We hope that a global market with antiviral and antibacterial properties of copper-containing plastics and other materials can be established in the next few years.”
The research team at the University of Chile, led by Dr. Aron Cortes, has conducted research on whether the new coronavirus’s response to copper is similar to other pathogens (currently ongoing). Cortez told reporters: “So far, the same family of viruses, including the previous SARS virus, have produced the same result: copper has always been anti-virus.”
He said that the effect of copper on the virus is like “soap on fat. When the metal ion contacts the viral envelope (a layer of glycoprotein), the envelope will rupture and the virus will be destroyed”.
