    Researchers developed a flexible biosensor for real-time detection of oral inflammation during dental examinations.

  • 2

    The TAHM biosensor measures TNF-alpha levels, which are linked to oral conditions like pulpitis and periodontitis.

  • 3

    Early detection of inflammation is crucial to prevent serious complications, including tooth loss.

  • 4

    The biosensor can accurately detect TNF-alpha in the oral environment while resisting interference from saliva.

  • 5

    With further validation, the biosensor could be integrated into routine dental visits for improved diagnostics.
