As disinfecting wipes and sprays fly off store shelves, companies are looking for new ways to keep surfaces coronavirus-free. Some are looking at repurposing UV light technology, a cleaning solution that’s been used for decades.Ava Robotics and the Massachusetts Institute of Technology partnered on a project to create a robot that uses UV-C light to disinfect large areas.“It was about a 4,000 square foot space. It was able to disinfect that in less than 30 minutes,” said Youssef Saleh with Ava Robotics.The purpose -- cleaning large, busy spaces of virus and bacteria, specifically coronavirus.“UV is not new. Robots are not new themselves,” Saleh said.“It's actually been in practice in hospitals for probably four decades plus,” said Dr. Eric Hill, the Chair of Emergency Services at Medical Center of Aurora. It’s usually used to sterilize rooms.“Anything that the light hits, it can kill. So it has to be in direct contact with the light beam and it has to be in contact for a certain period of time,” Hill said.“There are three factors of effectiveness of UV light, the first is the power itself,” Saleh explained. “Then there's the distance to the object that you're trying to disinfect, and then there is the amount of time.”"We cannot see it, it's the same kind of UV radiation you’d get from the sun,” Hill said. “It works by destroying the DNA and the RNA of the organism. And it doesn't affect just viruses, it affects bacteria, viruses, mold, and spores.”While it can kill germs, it can also do damage to us. UV light plays a role in diseases like skin cancer. “It is dangerous for humans to be in direct contact with it,” Dr. Hill said.That’s why the project with Ava Robotics and MIT also factors in safety for humans.“Safety elements have to be part of the solution, thought through, and understood,” Saleh said. The team is working on making the robot more adaptable to changing spaces, like warehouses, and potentially other large spaces like grocery stores and schoolsBut Hill says UV light isn’t a complete replacement for traditional cleaning methods.“It does not take the place of things like wiping something down,” he said. “But after you do that...adding in a UV light system can really hit in a broad area...and get all the microorganisms that were in there.”Hill also warns consumers that are interested in this to look at products closely.“Several hundred dollars is realistic for a good UV light system,” he explained. “We have seen much more of a demand of it, if you go on Amazon the amount of UV light products I’ve seen pushed out is incredible.” 2591

An Ohio company that makes bulletproof backpack shields is experiencing an increase in demand for its product due to concerns over school shootings."We've had, I would say, a 100 to 200 percent increase certainly in response," said Matt White, the director of marketing for ShotStop Ballistics, based in Stow.The backpack inserts are one-quarter inch thick and weigh about a pound. It's made from the company's Duritium technology, which can block bullets from handguns and some rifles. However, it does not protect against high-caliber weapons, like AR-15s.The shields come in hard or soft designs and cost 0.White said more parents have been inquiring and ordering the insert following the Feb. 14 school shooting in Parkland, Florida. Demand also increased after a 13-year-old boy died after shooting himself inside a middle school restroom in nearby Jackson Township."The fact that you're even here and we're talking about it, it's terrible," White said. "It's not something that we ever envisioned. It's not something that we had planned for, but the potential with what's out there now, it's one more layer of safety."White said the bulletproof product was originally meant as a clipboard for police officers to provide added protection during traffic stops.Some believe sending kids off to school with the shield only creates more fear and anxiety."It's not right. I mean, come on," said Dave Spearing who has grandchildren in the nearby Cuyahoga Falls School District. "Schools are safe."But Kendall Kubus, a recent Akron Archbishop Hoban High School graduate, sees it differently."I think it's protecting us against if that is a scenario, we have that protection and parents have that in their mind that, "Okay, my child is there. They're going to be safer."' 1819
