The fear of becoming infected with the new coronavirus by touching the shared surface has recently become widespread among the masses. As the number of COVID-19 surges, people are panicking about using door knobs, elevator buttons, and light switches. The Virginia Tech professor may have found a solution to this.
For the past few months, William Ducker, a professor of chemical engineering, has been working on developing surface coatings that can inactivate new coronaviruses when applied to common objects.
Since mid-April, he has been working with experts from the Department of Public Health at the University of Hong Kong to test the possibility of deactivating SARS-CoV-2.

The test results are excellent. Coating the glass or stainless steel with the new coating reduced viral load by 99.9% within 1 hour compared to the uncoated surface.
“It was an interesting experience. The entire campus was almost closed and ghosts were wandering around the empty halls of Goodwin Hall. But having such a clear goal was very exciting. I think it was a difficult time for many people who were bored, unhappy or scared. We were focused on making coatings.”
The new anti-coronavirus surface coating consists of cuprous oxide (Cu2O) particles bound to polyurethane.
Polyurethane-based materials have the advantage that they have already been used to coat many everyday objects. This new coating adheres well to glass and stainless steel objects as well as several other items used daily.
Researchers found that the new coating performed well in the hatching durability test and remained intact and alive for 13 days in water or multiple cycles of virus and disinfectant. Did.
Researchers are now waiting for funding to mass-produce movies. They also emphasized that the new coating does not replace other precautions such as hand washing, wearing masks and social distances.
