Researchers have created a unique atomic-scale identifications based on the irregularities found in 2D materials like graphene, making it possible to fingerprint them in simple electronic devices and optical tags. Because of the materials used, the small tags could be edible and coated onto medicines.
The counterfeit industry is a huge market with imports of counterfeited or fake agoods costing nearly $500 billion in lost revenue around the world annually, with counterfeit medicines accounting for nearly $200 billion alone.
The team is also showcasing the new technology through a smartphone app that allows people to check on their own the authenticity of a product by reading whether a product is real or fake.
The customer can scan the optical tag with the app that matches the 2D tag with the manufacturer’s database.
The researchers expect the patented technology and smartphone app to be available publicly in 2018.
When light is shone on graphene, tiny imperfections shine causing the material to emit light that can be measured as a signal, unique only to that small section of material. The signal can be turned into a digital fingerprint with a number sequence.
The study was published in 2D Materials.
