Scientists have created a practical edible graphene
shaoran2012A group of scientists from rice University have developed a technique for applying graphene marks on different surfaces – in particular, on food. The secret lies in the fact that graphene can turn almost any product containing carbon. As a “magic wand”, the researchers used a defocused laser beam. Objects to label steel paper, cardboard, cork, coal, freshly baked and toasted bread, coconut shells and potato skins. A kind of “ink” in this case was the complex organic carbon-containing polymer lignin, which forms graphene label under the laser exposure. According […]
