Overview

• The floss integrates microfluidic channels and synthetic molecularly imprinted polymers (eMIPs) to detect cortisol, a key stress hormone, in saliva.
• Designed for everyday use, the device collects saliva through the floss string and analyzes it via electrodes in the handle for real-time stress monitoring.
• The technology demonstrated accuracy on par with leading devices in a study published in ACS Applied Materials & Interfaces in April 2025.
• Researchers are forming a startup to bring the floss sensor to market, aiming to make stress and health monitoring accessible for routine use.
• The platform could potentially be adapted to detect other salivary biomarkers like glucose, estrogen, and cancer markers, enabling broader health applications.
