Despite its importance, disclosure in nanotechnology faces several challenges: 1. Complexity: The intricate nature of nanotechnology makes it difficult to convey technical details comprehensively. 2. Confidentiality: Balancing the need for disclosure with protecting proprietary information and trade secrets. 3. Regulatory Variability: Different countries have varying regulations and standards, complicating the disclosure process. 4. Public Perception: Ensuring that disclosed information is understandable to non-experts to avoid misinformation and fear.
