What if checking your stress levels was as simple as brushing your teeth? Researchers at Tufts University have made this a reality with their latest invention—a smart dental floss sensor that can measure cortisol, the body’s primary stress hormone, in real time.

This cutting-edge floss pick not only helps you clean your teeth but also tracks your stress levels through saliva, bringing advanced stress monitoring right into your daily routine—no needles, no labs, no extra steps.

🧪 How Does It Work?

The device looks just like a regular floss pick, but it’s secretly a biosensor. Here’s how it functions:

• As you floss, your saliva is absorbed by the string.
• The fluid moves into a small channel inside the pick and reaches special electrodes that detect cortisol.
• These electrodes use a technology called eMIPs (electropolymerized molecularly imprinted polymers), which can recognize and bind to cortisol molecules, kind of like a lock and key.

This technology doesn’t require expensive antibodies or special receptors. Instead, it creates a polymer mold of cortisol and detects it accurately every time.

🌟 Why Is This a Big Deal?

Chronic stress can lead to major health issues like high blood pressure, heart disease, weak immunity, depression, and anxiety. But until now, most stress tracking relied on questionnaires or expensive clinical tools.

This new sensor is:

✅ Accurate – Comparable to top-performing lab sensors
✅ Non-invasive – Uses saliva, no blood required
✅ Easy to use – Fits into your normal flossing habit
✅ Affordable – No special training or devices needed

And it’s just the beginning. The same sensor technology can be used to detect other health markers in saliva, such as glucose for diabetes, estrogen for fertility, or even cancer markers—all through a simple daily routine.

🧠 What This Means for Doctorpreneurs
