Biosensor Glasses Monitor Glucose in Tears

Biosensor Glasses Monitor Glucose in Tears
A biosensor able to monitor diabetes through tears could be built into eyeglasses to eliminate the need for needles.

The biosensor created by researchers from the University of São Paulo and the University of California is embedded in the nosepiece of the glasses. When the sensor detects the glucose oxidase enzyme, it will trigger an alert processed in the arm of the glasses and then sent in real-time to a paired device. Although the biosensor eliminates the need for fingerpicks, the wear must still produce tears using an eye-sensitive substance.

According to the team, the biosensor can be altered to detect different types of compounds in the blood, such as vitamins or alcohol, as well as certain types of cancer and degenerative diseases.
