While it is fashionable to wear tattoos, in the future these tattoos may provide more than aesthetics, because researchers at Tufts University have created a silk-based material that can be placed under the skin and that glows more or dims under a lamp when exposed. to different levels of oxygen in the blood.

Near really functional tattoobecause it tells you how much oxygen you’re using during your workout, but it’s also capable of measuring blood glucose at any time of the day, or even monitoring a number of different blood components.

This sensor is currently limited by oxygen levels and consists of a gel formed from the protein components of silk called fibroin.

When the wax is assembled into a gel or film, it adapts, creating a structure that stays under the skin for weeks to a year, and when the wax breaks down, it is compatible with the body.

so he can constantly monitor substances in the bloodwhich can be a big advantage when tracking certain human conditions.

As an example, the researchers cite diabetics who have to draw blood regularly to decide what to eat or when to take their medications, but instead, the researchers tried to make monitoring much easier with these types of tattoos.

Silk is a remarkable combination of many excellent properties.” indicates that David Kaplanprofessor of engineering at the Tufts University School of Engineering and principal investigator of the study.

We can turn it into films, sponges, gels and more. Not only is it biocompatible, but it can contain additives without changing its chemical composition, and these additives can have sensory properties that detect molecules in their environment. The oxygen sensor is a proof of concept for a range of sensors that we could build.“, Add.

And the fact is that the chemical composition of silk proteins contributes to the collection and retention of additives without changing their properties.

To create this oxygen sensor, the researchers used a supplement called PdBMAP which glows when exposed to light of a certain wavelength, and this glow has an intensity and duration proportional to the level of oxygen in the environment.

The silk gel is permeable to surrounding fluids, so PdBMAP sees the same levels of oxygen in the surrounding blood. PdBMAP is also useful because it glows or phosphoresces when exposed to light that can penetrate the skin.

In experiments, this implanted sensor managed to determine the level of oxygen in animal models in real time. and accurately track high, low and normal oxygen levels.
