Despite the benefits, harmonizing nanotechnology faces several challenges:
1. Rapid Advancement: The field evolves quickly, making it hard for standards to keep up. 2. Interdisciplinary Nature: Different scientific disciplines may have varying methodologies and terminologies. 3. Regulatory Differences: Different countries have different regulatory landscapes, complicating international harmonization. 4. Resource Constraints: Developing and implementing standards requires significant resources, which may not be available to all stakeholders.
