<p class="has-text-align-justify">A tattoo that will change colour to reflect the changes that occur in the blood glucose levels has been created by German scientists. So far, a team of scientists from the Technical University of Munich have successfully tested out the same on the skin of pigs. Led by a chemical engineer, Dr. Ali Yetisen, the team used a colour-changing dye to reflect changes in blood glucose levels, with a view to help people manage diabetes. They also tried on picking up albumin, a marker of kidney disease. They used another dye to measure the pH level in human blood.</p>

<p class="has-text-align-justify">The dyes used react to changes in the three biomarkers in the interstitial fluid. This fluid acts as a storehouse of nutrients including glucose. The glucose level in interstitial fluid decreases and increases in response to the fall and rise in blood glucose levels. The researchers made the point that the glucose sensor picks up the chemical changes in blood glucose levels, leading to a change in the dye from yellow to dark green.</p>



<p class="has-text-align-justify">The albumin sensor turns green indicating presence of albumin. The pH sensor uses red and blue dye. The sensor turns yellow to blue when the pH level is normal for human blood.</p>



<p>Here&#8217;s how it happens-</p>

<p class="has-text-align-justify">The dyes, apart from the Ph level, are not reversible as of now but the scientists said that the study represents a first step in developing tattoos to help people with diabetes and kidney disease to manage their conditions in real-time.</p>



<p class="has-text-align-justify">The scientists mentioned that body modification by injecting pigments into the dermis layer is an old custom. A functional cosmetic technology was found by combining colorimetric biosensors and tattoo artistry. Dermal tattoo sensors function as diagnostic displays by exhibiting colour changes within the visible spectrum in response to changes in glucose, pH, and albumin concentrations.</p>
