Saliva-monitoring chip to track bone loss, diabetes, inflammatory markers

Washington University’s Erica Lynn Scheller and Shantanu Chakrabartty are developing a gum or dental device-worn sensor to detect early signs of  disease by analyzing saliva or gingival crevicular fluid.

The sensor plus electronic chip is a few millimeters-cube in volume and measures disease-specific peptides.  A wireless ultrasound device reads the peptide levels and connects to the cloud.

The first use will be monitoring  bone breakdown during periodontitis. The goal is to track multiple inflammatory and stress markers and to monitor diabetes.
