Modifying metal surfaces to kill viruses instantly

Modifying metal surfaces to kill viruses instantly Today’s Video of the Day from Purdue University describes a laser treatment that can instantly wipe out infectious bacteria on metal surfaces. 

Pathogenic bacteria can live on surfaces for hours or even days. The new technique from Purdue will make it possible to protect frequently-touched surfaces, like metal door knobs, from lingering germs.

“Copper has been used as an antimicrobial material for centuries. But it typically takes hours for native copper surfaces to kill off bacteria,” explained study lead author Professor Rahim Rahimi. ” Modifying metal surfaces to kill viruses instantly We developed a one-step laser-texturing technique that effectively enhances the bacteria-killing properties of copper’s surface.”

Also the producing surfaces are capable of preventing viruses. They will require an especially fine level of precision, as they’re smaller than bacteria. But Vladimir Baulin, a biophysicist at the Universitat Rovira i Virgili in Spain. And believes similar techniques can be used with viruses, including coronavirus.

Therefore the bacterial pathogens can live on surfaces for days. So you will find frequently touched surfaces such as doorknobs could instantly kill them off? Purdue University engineers created a laser treatment method that could potentially turn any metal surface into a rapid bacteria killer and help fight the spread of these germs and pathogens as well as the deadly coronavirus.  You can also find that Lasers turn metal surfaces into bacteria killers helping with this wide spread virus.  Also the use of Solutions of alcohol should be 70% and left on surfaces for atleast 30 seconds or more.
