Tiny Mouth Patch Detects Gum Disease Before Symptoms Appear
Texas A&M researchers developed a wearable oral biosensor using graphene-MXene technology that can detect inflammation at the femtogram level, catching gum disease long before visible damage occurs.
Key Takeaways
- The graphene-MXene biosensor detects TNF-alpha inflammation markers at concentrations as low as 18.2 femtograms per milliliter
- Developed by a multi-university team led by Texas A&M, with collaborators at Michigan State and the University of Michigan
- Published in Science Advances, the patch was validated in guinea pig studies showing detection of inflammation before visible symptoms
