flag German researchers created a gum that detects flu in saliva within 30 minutes using a safe, herbal signal.

flag Researchers in Germany have developed a chewing gum with a molecular sensor that detects influenza by reacting to the virus's neuraminidase protein, releasing thymol—a compound in thyme—within 30 minutes of exposure to flu-positive saliva. flag The resulting herbal taste signals infection, with lab tests showing no harm to human or mouse cells. flag The team at Würzburg University aims to begin human clinical trials in two years to test the gum’s ability to detect flu during early or pre-symptomatic stages. flag If successful, the technology could offer a rapid, low-cost, and accessible screening tool for high-risk settings like schools and hospitals. flag The findings were published in ACS Central Science.
