How Can Nanotechnology Be Used in Anti-counterfeiting?
Nanotechnology offers innovative solutions for anti-counterfeiting through the development of nano-barcodes, nanotags, and holographic images. These features can be embedded in products, documents, and currency to provide unique identifiers that are difficult to replicate or tamper with. For example, nanoparticles with unique optical properties can be used to create security inks that change color under different lighting conditions.
