Researchers Develop Biosensing Tattooadmin
“Using a specialized ink, they have come up with a biosensing tattoo, one that will change color depending on your blood sugar levels,” IFLScience.com reported. Known as DermalAbyss ink, this specialized ink will be able to track pH levels and sodium and glucose concentrations in the blood stream and then changes color accordingly. Too much glucose in the person’s blood? The ink becomes brown. When too much sodium is present, the ink will turn green. Changing pH levels are indicated using purple and pink ink.
The ink is able to identify these changes by monitoring the person’s interstitial fluid – “a substance that surrounds the tissue cells of an animal” – that is constantly flooded with water, ions, and small solutes.
So far, the ink has only been tested on pig skin – but the results have all been positive. However, human trials are still needed to test for potential allergic reactions and technological faults.
