`What if, when confronted with a COVID-contaminated countertop, cockpit or control panel, a person could decontaminate the entire surface by zapping it with a handheld ultraviolet light?<\/p>\n

Technology that UND is testing and helping to develop could make it possible for people to do just that. And if the testing is successful, the U.S. Air Force and the global food-services industry are just two of the industrial behemoths that are likely to be interested.<\/p>\n

Supported by a $1.5 million grant from the North Dakota Department of Agriculture<\/a>, SafetySpect Inc. \u2013 a California-based company \u2013 is bringing its virus-fighting solution to multiple UND labs for experimentation.<\/p>\n

And \u2013 upon setting up shop in the UND Center for Innovation \u2013 they\u2019re aiming to establish a Midwest footprint.<\/p>\n

By the end of the calendar year, SafetySpect\u2019s goal is to have dozens of prototype UV light scanner\/disinfection systems, manufactured in North Dakota, ready for use in the field.<\/p>\n

Joe Vacek<\/figcaption><\/figure>\n

On Sept. 1, leaders of SafetySpect met with Joe Vacek, associate professor of aviation, at UND Flight Operations for a brief demonstration. And over the course of the fall semester, the SafetySpect system will be tested in UND labs, where researchers will \u201ccontaminate\u201d various materials and then assess the light\u2019s safety and effectiveness at decontaminating them.<\/p>\n

Quickly and safely<\/strong><\/p>\n

Sitting in the cockpit, SafetySpect president and CEO Kenneth Barton aimed a handheld spotlight emitting a deep glow, reminiscent of a black light. Nearby, a tablet showed a live feed of the spotlight\u2019s target: the control panel of a UND Piper Archer aircraft.<\/p>\n

\u201cWe\u2019re using the Contamination and Sanitation Inspection and Disinfection (CSI-D) tool to identify respiratory droplets on sensitive airplane equipment that you cannot traditionally just spray down with disinfectant,\u201d Barton explained.<\/p>\n

Continuing to aim the device, Barton swept across high-touch areas such as the yoke of the craft. On the tablet display, SafetySpect\u2019s optical imaging technology highlighted saliva enzymes as bright white spots.<\/p>\n

The UVC LEDs that \u201cbrightened\u201d the enzymes can also render virus-carrying droplets inert with a strong, brief exposure. The entire process is recorded and captured on the tablet.<\/p>\n

\u201cAfter that, a sanitation crew can get rid of the respiratory droplets in a safe manner, because any virus would have been effectively neutralized by the UVC,\u201d Barton said.<\/p>\n

Following another scan, the bright white spots were gone. \u201cAnd there has been no cross contamination by any viral issues,\u201d Barton concluded.<\/p>\n

New approach<\/strong><\/p>\n

SafetySpect\u2019s CSI-D tool was designed originally for the food industry, for use in restaurants and other institutional kitchens. The tool\u2019s early models targeted various biologics that can trigger food poisoning and other ailments. The federal government recognizes the value of that work; so, since 2019, the company has been working with the USDA to improve the CSI-D tool for commercialization.<\/p>\n

\u201cThen when COVID hit, we realized there is an enzyme in human respiratory droplets and saliva,\u201d Barton said. \u201cSo, we adapted the device to scan for that.\u201d<\/p>\n

As demonstrated in the Piper Archer cockpit, the device uses UVC light to identify a contaminant, then an operator can crank up the UVC to essentially kill the virus. This use of UVC isn\u2019t novel, but SafetySpect\u2019s pairing of a tablet device to tune its visual output, as well as record the sanitation process, can create better record-keeping and more accountability in matters of public health.<\/p>\n

\u201cAll of the process will be recorded, time-stamped, dated and location-stamped in a digital record in the cloud,\u201d said Fartash Vasefi, chief technology officer at SafetySpect. \u201cOther UV systems offer only the disinfection. They don\u2019t have the imaging and documentation to go with it.\u201d<\/p>\n

Developed on campus<\/strong><\/p>\n

Vasefi described where the University of North Dakota fits into the picture with SafetySpect\u2019s product development.<\/p>\n

\u201cThe safety is key,\u201d Vasefi said.<\/p>\n

Kouhyar Tavakolian<\/figcaption><\/figure>\n

In the lab at the College of Engineering & Mines run by Kouhyar Tavakolian, associate professor, director of the biomedical engineering program and principal investigator on the SafetySpect project, researchers will shine the SafetySpect device on a number of surfaces. Among the surfaces will be samples of the plastics, metals, digital screens and upholstery typically found in airplane cockpits.<\/p>\n

While an operator conducts the scan, sensors will be placed on the operator\u2019s body in order to detect the intensity of back-reflected UV light. Tavakolian\u2019s team will study the results to gauge how much personal protection equipment will be needed for safe operation.<\/p>\n

\u201cAll of this development has to be tied into experiments and validation, and that\u2019s what\u2019s happening at UND,\u201d Vasefi said.<\/p>\n

The airline industry, ravaged as it has been by the coronavirus pandemic, has become increasingly interested in SafetySpect\u2019s technology, according to the project leads. What better place to test the technology on aircraft than the nation\u2019s top flight school?<\/p>\n

Tavakolian wants to create a space where he and his team can show the repeatability of the device\u2019s saliva detection abilities. He is also working with virologist Nadeem Khan at the School of Medicine & Health Sciences to understand how intense the UV light needs to be, and how long is needed for appropriate exposure, to disable viruses. COVID-19 cannot be used in testing on campus, but other pathogens can be tested at the School of Medicine & Health Sciences.<\/p>\n

\u201cWe think that, in the future, this could be useful for any pathogen that can be transmitted through respiratory droplets,\u201d Tavakolian said. \u201cRemember, even if a vaccine comes, the coronavirus is not going to vanish overnight. Once we have a unit such as the CSI-D tool, we can always improve its accuracy and its size, and we also can always improve on the safety of it.\u201d<\/p>\n

New presence<\/strong><\/p>\n

With an established presence at UND, SafetySpect is also working with manufacturer ComDel Innovation in Wahpeton, N.D., to produce the shells for the UVC spotlights\/camera prototypes and assemble the finished products.<\/p>\n

Barton, SafetySpect\u2019s CEO, said the resources and business climate in North Dakota present an exciting opportunity for a potentially industry-altering technology.<\/p>\n

For UND, the collaborative project shows the value of UND\u2019s research and development capabilities, said John Mihelich, interim vice president for research and economic development.<\/p>\n

\u201cWe\u2019re focused on increasing these types of partnerships in order to move our research and development forward, have an impact and bring new industry partners to the state,\u201d Mihelich said.<\/p>\n

Tavakolian is keen on seeing whether the product can help with the COVID-19 situation affecting everyday life around UND and communities across the country.<\/p>\n

\u201cYou can have it in schools, restaurants, airplanes and the like, so we should be able to get some user response,\u201d Tavakolian said. \u201cHopefully that will help the company and the whole idea to go forward quickly.<\/p>\n","protected":false},"excerpt":{"rendered":"
