Risk assessment in nanotechnology is complex due to several factors:
Novelty: Many nanomaterials are newly developed, with limited historical data available for analysis. Size and Shape: The properties of nanoparticles can vary significantly based on their size, shape, and surface characteristics, complicating standardized testing. Interdisciplinary Nature: Nanotechnology spans multiple scientific disciplines, requiring collaborative efforts for comprehensive risk evaluation. Regulatory Gaps: Current regulations and guidelines may not adequately address the unique aspects of nanotechnology, leading to inconsistencies in safety standards.
