Innovative Flu Test Using Chewing Gum or Lollipops Developed by Researchers

Thu 2nd Oct, 2025

Researchers have developed a groundbreaking rapid test for influenza that utilizes a unique method involving chewing gum or lollipops, as reported by the University of Würzburg. This innovative diagnostic tool allows individuals to detect a flu infection by simply chewing gum, releasing a specific flavor compound upon contact with saliva from infected individuals.

The new testing approach is designed to provide results within minutes, eliminating the need for laboratory facilities, electricity, or medical personnel. According to the research team, led by Lorenz Meinel from the University of Würzburg along with experts from Braunschweig and Cologne, this method could significantly enhance global influenza detection and management efforts.

At the core of the testing system are thymol, a natural compound found in thyme, and a virus-specific sugar molecule. When exposed to active influenza viruses in a patient's saliva, thymol is released, producing a distinct flavor that can be easily recognized by the user. This system can be customized to present various flavors such as sweet, bitter, or salty, making it suitable even for children.

Moreover, the researchers indicate that the underlying principle of this diagnostic method could be adapted for other pathogens by substituting the virus-specific sugar molecule with a peptide specific to bacteria. The research team is currently focused on integrating these sensors into chewing gum and lollipops, working alongside a startup to make this diagnostic tool widely accessible. The anticipated timeline for development is approximately four years.

The introduction of such a diagnostic method has the potential to greatly enhance the accessibility of viral and bacterial infection testing, particularly in settings like schools, daycare centers, and nursing homes. It also holds promise for implementation in low-income countries, where conventional and costly laboratory diagnostics may not be feasible.
