LA JOLLA, Calif. (KGTV) - Researchers at UC San Diego have developed a new way to field test for Fentanyl, a dangerous opioid that is deadly even in trace amounts.Similar to diabetes testing strips that measure glucose levels, the scientists at the Center for Wearable Sensors created a testing strip that can detect Fentanyl."You simply swipe the surface and collect the sample and analyze it in one or two minutes, on the spot," says Joseph Wang, the Center's Director.The strip uses electrochemical carbon and silver electrodes. The meter runs currents from the electrodes through the sample. Based on how the material reacts, it can tell if Fentanyl is present, down to a nanogram level.They recently published their success in an article in the Chemical and Engineering News.The practical applications of the testing strips are wide-ranging, says Wang. He believes that law enforcement, first responders, border patrol agents and post office workers would use this new technology to test any unknown substance.Recently, law enforcement agencies have been looking for ways to field-test for Fentanyl, since any contact with the drug can lead to an overdose or even death.The San Diego Sheriff's Department bought 15 TruNarc devices this past fall. Those scan materials and tell what kind of drugs are present. But they cost nearly ,000 each.RELATED: New device keeps first responders safe from dangerous drugs at crime scenesWang says his lab's testing strips can be made for pennies, and the meters needed to analyze the sample could cost less than .Addiction advocates also believe this could save lives among drug users, by giving them an easy, cheap way to test the drugs they take and make sure they're not laced with Fentanyl. Wang says his test is simpler to use than current testing strips.RELATED: Drug users can now test if Fentanyl is in the drugs they are using before injection"This could save lives," says Wang. 1943

LEXINGTON, Ky. -- A teenager died Sunday after being shot at a mall in Lexington, Kentucky. The Fayette County Coroner's Office identified the victim as 17-year-old Kenneth Wayne Bottoms Jr., of Lexington. Bottoms was transported UK Medical Center at about 4 p.m where he was pronounced dead at 6:10 p.m.Two other victims were also injured in the shooting, which police say happened in front of a Bath and Body Works at Fayette Mall. Police Chief Lawrence Weathers said at least one of the victims and a suspect knew each other. They may have had an interaction prior to the shooting.Officers are currently interviewing witnesses. No suspects are in custody at this point.Scripps station WLEX interviewed one Lexington shopper who was inside Bath and Body Works. She says she witnessed an argument outside of the shop that escalated when someone pulled out a gun."Held it up at face level... and he shot four shots off," said the shopper.The shopper, who wished to remain anonymous, says she was escorted with others toward the back of the store."We stayed in the bathroom until police got us out of the service door to Bath and Body Works, and they walked us around all of the blood to take us outside," said the shopper.Mark Thomas was inside his shop, Bourbon Creek, when he saw a group of people run by with sheer panic on their faces. His store was packed at the time, so the retired Lexington police detective quickly jumped into action."We had several customers that were wanting to leave, and we have a back door into the parking lot, so we were able to help evacuate people through the store. That's one of the things you want to do as a former police officer is you want to facilitate people getting to safety," said Thomas. 1742

Liliana Gallegos says she could not breathe and had chest pains when she was infected with the novel coronavirus.“Back then, even myself, I wasn’t masking up,” Liliana Gallegos said. “I was like, ‘it’s not that serious. It was like a cold or flu.’”It was far from a cold or flu. Gallegos was diagnosed with COVID-19 in April, and she wasn’t the only one in her household. Her 63-year-old father and her children also got infected. Later, her fiancé got sick.“He passed it on, and all his co-workers caught COVID. It just spread, and we were not cautious about that at that time,” said Gallegos.Gallegos recovered 17 days later. The experience gave her a new perspective.“I think it’s so important to take the precautions they are telling us. Six feet apart, sanitize, wear your mask,” she said.More than 1,000 hospitals in the U.S. are teaming up to encourage everyone to stay safe.The Every Mask Up (#EveryMaskUp) campaign provides vital health resources and has developed messages on a variety of digital platforms to get the word out.Medical experts say wearing a mask is the best chance of slowing the COVID-19 pandemic.Right now, more than 13 million Americans are infected, and more than 250,000 have died. 1220
