Smart Dental Floss Measures Stress via Saliva
A new dental floss pick can sample saliva for stress markers like cortisol, offering a novel, non-invasive method for daily health monitoring via a common hygiene product.
Scientists developed a dental floss pick equipped with embedded electrodes that can detect and quantify cortisol levels in saliva. This device, detailed by its creators, leverages a polymer casting technology to integrate biosensors directly into the floss, turning a routine hygiene step into a diagnostic opportunity.
Cortisol, often termed the 'stress hormone', fluctuates with mental and physical stress. Monitoring these levels daily can offer insights into an individual’s wellbeing, aid in stress management, and even indicate broader physiological changes. The floss provides a less invasive and more frequent sampling method than traditional blood tests or even laboratory-based saliva tests.
The underlying polymer casting technology is also adaptable. Researchers suggest it can be reconfigured to detect other biomarkers, such as estrogen for fertility tracking or glucose for diabetes management. This flexibility could lead to a suite of highly personalized, disposable diagnostic tools embedded in various consumer products.
Moving forward, the challenge will be to ensure the accuracy and reliability of such consumer-grade diagnostics, and to manage the resulting influx of personal health data responsibly. Your daily floss could become a crucial sensor, making it even more important to understand what data it collects and who has access to it.
