An experimental flu test could detect the virus right on the tip of your tongue.

Researchers in Germany have potentially discovered a new way to spot influenza through an edible test, potentially like a piece of gum or a “thin film.”

When someone pops the test in their mouth, chemical sensors will either produce a taste or not – signaling the presence of an infection.

The scientists created a tiny molecule that reacts only when the flu virus enzyme, called neuraminidase, is present. This is the enzyme that infects and spreads.

The presence of the virus in the mouth or saliva will trigger this reaction, release thymol (a flavor compound) and produce a strong
