UV Light Based Biosensor Can instantly Detect Stress Levels

Scientists at the University of Cincinnati have designed a biosensor, which uses a very basic technology to determine levels of stress hormones in, blood, sweat, saliva, or urine. The researchers expect that the testing device will be commercially available soon so that people can assess their stress levels anytime. The device can be used at airports to monitor the stress level of pilots, to make sure that they are prepared to do their job safely.

The researchers specified that stress is associated with several physical disorders such as high blood pressure, diabetes, and physiological or neurological disorders. By measuring stress biomarkers, this simple test will help patients to maintain their health and modify their lifestyle regularly notifying them. The recently designed biosensor requires just a drop of sample to measure several stress markers simultaneously.

The biosensor is based on the principle of optical absorption, in which a UV light emitting diode is equipped. With the help of absorption levels of stress biomarkers in biological samples, the device provides an indication of the stress biomarkers’ levels present in the sample.

On a similar note, the U.S. Food and Drug Administration (FDA) has approved the first ever test, which can detect antibodies generated against Zika in the human immune system. The diagnostic test is officially certified for sale across the US. !8 other tests have already been designed and developed but were assessed to under emergencies only.

The test works by detecting the Zika antibodies that the body’s immune system generates and releases into the bloodstream. For confirmation, a clinical study was conducted in which 807 samples were analyzed through this test. However, the test will give appropriate results for only those patients, who would be experiencing signs and symptoms of Zika infection.

In rare cases, the test may reveal negative or false results, if the sample would be extracted within four days of symptoms onset.
