The future of health monitoring may be just around the corner. Scientists have recently developed a superhydrophobic biosensor that can detect vapors in the body and may one day be used to monitor a person’s health. The sensor is made up of two layers of material, with one layer containing a hydrophobic coating and the other made up of a metal oxide. When a vapor enters the sensor, it interacts with the metal oxide layer, which then triggers the hydrophobic coating to change its structure and release a signal to the user. This could be used to detect a variety of different health indicators, such as glucose levels and cancer markers. The potential applications of this biosensor are endless, and could revolutionize how we monitor our health.
