Scientists Create Dental Floss for Measuring Stress Levels

Scientists have created dental floss for the rapid measurement of stress levels. Researchers from Tufts University (USA) have developed dental floss that can determine the cortisol levels in a human body - a saliva sample is enough for this. The saliva is drawn through a barely noticeable channel in the floss, then enters the handle and tongue. The sample is then distributed across electrodes, which determine the cortisol level. Scientists clarified that the dental floss shows high accuracy in measurements, but tracking markers alone is insufficient for the initial diagnosis of diseases.
