Natalie Plank and Victoria University colleagues have developed an estrogen sensor that sends an electrical signal when it detects the hormone in liquids. The device attracts DNA pieces called aptamers, which attach to estrogen molecules, to carbon nanotubes. The nanotubes act like transistors, emitting an electric signal if estrogen molecules are present.
The technology could be used with body fluids to track fertility, or test for hormone contamination in waterways.
ApplySci believes that hormone sensing will be a focus of the next generation of wearables, and will improve health monitoring.
