"Sweat-based Biosensor: A Breakthrough in Fertility Hormone Monitoring"

Researchers have developed a wearable biosensor in the form of a ring that can detect hormone levels, specifically oestradiol, in human sweat. The biosensor combines microfluidics, electrode technology, and aptamers to provide real-time hormone measurements, offering a non-invasive and convenient alternative to traditional methods of hormone monitoring. The technology has potential applications in fertility tracking, women's health, and hormone therapy, and could pave the way for the development of sweat-based biosensors for multiple hormones.
