Counterfeiting in nanotechnology involves the illegal production and distribution of fake or unauthorized copies of nanoscale materials, devices, or products. These counterfeit items can range from [nanomaterials]() such as nanoparticles and nanotubes to more complex devices like [nanosensors]() and nanoelectronics. The presence of counterfeit nanotechnology can compromise product performance, safety, and reliability, posing significant risks to consumers and industries.
