Drawing on the body, in fact, - a useless thing. Gone are the days when the tattoo was determined by the degree of authority of the owner. Today pectoral figure is purely decorative. However, recently, US scientists from the laboratory Draper figured out how to make use of the tattoo.
Researchers have developed a tattoo sensor - a new type of tattoo. Amazing sensors in the form of tattoos will monitor the health of people. Scientists have created a special dye that reacts to changes in the level of glucose in the blood and other vital parameters.
Made this tattoo inks can be infallible indicator, because an increase in glucose pectoral turn yellow pattern, with decreasing appear purple.
Medical tattoos will help diabetics feel comfortable, because now they are forced by special devices twice a day to measure blood levels.
"Moskovsky Komsomolets" reports that experts from Northeastern University, USA, is currently working with the animals. The discovery injected under the skin test tiny polymer particles - nanosensors.
Heather Clark, Director of Research, and his colleagues have come up with a special ink consisting of polymer beads that are coated with a biocompatible material. Content beads composed of elements responsive to the fluorescent emission certain chemicals.
Introducing the ink under the skin, a quantitative analysis of blood analyzed radiation tattoos. In the development of "smart tattoo" is used a substance that can detect the presence of sodium (an indicator for dehydration of tissues), and lights up when the level is low.
Today, experiments were carried out only in rodents, but scientists hope in the near future to make such a tattoo people.
