A group of biotechnology researchers at the Massachusetts Institute of Technology and Harvard University replaced the typical ink used in tattoos with a biosensor paint that responds to changes in the interstitial fluid through which the substances pass from the blood to The tissues, and vice versa.
The idea is that the tattoo of the future will be able to detect changes in pH, sodium and glucose levels, which can be very useful especially for people with diabetes, and constantly need to be monitored.
So far, DermalAbyss (name of the project) has only been tested on the skin of pigs, but there are good chances that it will evolve into clinical trials in humans, although researchers recognize that they have a long way to go before the product can come To be placed on the market. As it can be read on the MIT website, “This is a research project, and there are currently no plans to develop Dermal Abyss as a product or to conduct clinical trials.”
So far four biosensors have been investigated, reacting to three areas of biochemical information in body fluid: the pH sensor changes from purple to pink, the glucose sensor changes between blue and brown; The sodium and a second pH sensor glow brighter under UV light. The idea is for these tattoo indicators to be as accurate as possible. In a clinical situation, this “interface” should be as reliable as a blood test, “and we’re definitely not in that phase yet,” the researchers reveal.
