A nanomaterial registry is crucial because it serves as a centralized source of reliable data. This is essential for several reasons: 1. Safety and Regulation: It helps regulatory agencies assess the potential risks associated with nanomaterials. 2. Research and Development: Researchers can access standardized data to accelerate innovation. 3. Commercial Applications: Companies can use the registry to find suitable nanomaterials for their products. 4. Interdisciplinary Collaboration: Facilitates collaboration across various fields like medicine, electronics, and environmental science.
