American scientists have discovered special labels that will help determine the suitability of food or cosmetics. Experts described their invention during the annual National Congress and Exhibition of the American Chemical Society, which was held yesterday in Washington, writes Gazeta.Ru.

It is reported that the stickers are made of paper, which is processed by a special indicator substance - inorganic particles. Interacting with potentially dangerous chemical compounds, they change their color.

The inventor Silvana Andreescu said that her stickers can be used for different purposes, including the identification of dangerous bacteria in food.

A team of scientists is hoping that soon they will be able with the help of wonderful stickers to identify E. coli, salmonella and other harmful microorganisms.

Earlier it was reported that specialists created a collapsible paper battery, which works at the expense of special bacteria. The invention may be used in biosensors for monitoring glucose levels in diabetics and other medical devices that consume little power. help to find out in which region produced such drinks as wine or tea.
