Thousands of years ago tattoos were used by people to underline their social status and protection from evil spirits. Now everyone puts their own meaning in the drawings on his body, reflecting his worldview, traits of his own character and his love for anyone. It seems that in the near future, the tattoo will begin to provide to others, and even to the owner — for example, to notify the exacerbation of chronic diseases. Perhaps the figures on your body will save the lives of their owners.
Usually, the tattoo ink is composed of soot, animal bones, tree resin and a variety of chemical compounds, the concentration of which determines the color of the paint. To make tattoo on the body could prevent exacerbation of chronic diseases, scientists propose to replace the conventional inks are those that change color when you change the level of various substances in the human body.
At the heart of these inks are so-called acid-base indicators. Almost every one of us knows what it's like in chemistry class we used them soaked strips of paper that when placed in different solutions change their color depending on their level of acidity. Adding these substances in the composition of the ink, the scientists were able to do so that the paint will change its color when the level of glucose, which is important for people with diabetes. Other inks react to changes in the level of the protein albumin, which can tell us about the state of the liver.
Remember these indicators from chemistry lessons?
Tattoos with a new type of ink was applied on porcine skin, which is very close in structure to the human. Dye was injected with a special machine in the skin layer called the dermis — is to penetrate the paint and when applying the usual tattoos.
the Structure of human skin
Scientists have developed the ink was yellow, and they react to changes in the body of the pig in different ways. So, at higher glucose levels one tattoo was dark green, and another tattoo if you change the protein level of albumin was found a light green shade. The owners of such tattoos will be able to quickly learn about the increase of sugar level in the blood, or about the improper work of the liver or kidneys.
change the color of the tattoo increasing the acidity, glucose and albumin
People To be able to accurately recognize the color change of the tattoo, the researchers developed a special application for smartphones. To learn about the state of his health, the future owners of tattoos-chameleons will just hover the camera of your mobile device.
Scientists plan to improve the technology and create ink that can prevent the emergence in humans of viruses that can cause the development of dangerous diseases. If the established scientists of the dyes prove their safety, changing the color of the tattoo can be a durable tool for tracking patients ' health condition.

Of Course, technology is not cheap — the price of the tattoo depends on the complexity of the drawing and can reach several tens of thousands of rubles. Today, craftsmen use very expensive equipment, which also increases the cost of tattoos. But in ancient times, by drawing pictures on the body could hardly have cost any money because the paint was almost completely made of soot, and the introduction under the skin used rough .
