It is usually difficult to tell fakes from Real products. But with the help of scientists a new method that can mark items/objects with (Atomic Fingerprints) to keep fake products from either entering on leaving the market.
A professor of physics at Lancaster University in the UK and chief technology professor Robert young and his friends announced a really simple technique for checking, the authenticity of an object
The anti-counterfeiting method, published online in (ArXiv)the open-access preprint journal from Cornell University, has two components: a unique mmolecular pattern
This really unique pattern is created by intentionally fabricating flaws into an atom-thin layer of material, such as graphene oxide. Flaws may include removing a carbon atom, or adding extra oxygen atoms, or creating a ridge of atoms according to the researchers. Once the flaw is set, the material is incorporated into an ink and then, using an inkjet printer, printed onto a hologram, which can be added as a label to any product.
Then to confirm the presence of the atomic pattern, a person would use a smartphone camera and its flash to photograph the label.The flash excites the atoms, which produce a different color based on the pattern. A corresponding app can instantly check the image and confirm if the label is real, authentic or not.
