Breaking New Ground in Cortisol Measurement

Imagine instantly knowing your body’s stress levels without stepping foot in a doctor’s office! A groundbreaking study led by Andy Yeh, a biomolecular engineering expert at UC Santa Cruz, reveals a new artificial biosensor that could redefine the way we measure cortisol—the body’s main stress hormone.

The Importance of Cortisol

Cortisol plays a vital role in regulating essential bodily functions, including blood pressure and metabolism. However, an imbalance in cortisol can lead to serious health issues. Traditionally, testing for cortisol levels required clinical visits, but that’s about to change.

Enter the Luminescent Sensor

Yeh has developed a luminescent sensor that detects cortisol in blood or urine samples. By binding with cortisol, the sensor emits light—a clear indicator of hormone levels. This innovation, published in the Journal of the American Chemical Society, shows the potential to measure cortisol across all health-relevant levels.
