What are the Challenges in Developing Security Inks Using Nanotechnology?
Despite the advantages, there are several challenges associated with the development and application of nanotechnology-based security inks:
Cost: The production of nanoparticles can be expensive, which may limit their use in some applications. Stability: Ensuring the long-term stability of the nanoparticles within the ink matrix can be challenging, especially under varying environmental conditions. Regulation: The use of nanoparticles in products is subject to regulatory scrutiny to ensure they are safe for human use and the environment.
