A team of researchers at UT Dallas has developed a handheld electrochemical sensor that can accurately detect fentanyl in urine within seconds, with a 98% accuracy rate. This groundbreaking device eliminates the need for time-consuming lab analysis and could be used for rapid screening in various situations. The team is also working to expand its capabilities to detect fentanyl in saliva, which could greatly inform treatment decisions for overdose cases. The ultimate goal is to develop a test for fentanyl in saliva, which could greatly improve emergency response efforts. The sensor works by using a molecular cagelike trap with naloxone as the “cheese” to capture fentanyl. This technology has the potential to make a significant impact in the fight against the ongoing opioid crisis.
