1. Regulatory Approvals: Governments and international bodies often require regulatory approvals before nanotechnological products can be brought to market. Agencies such as the FDA and EPA in the United States have specific guidelines for nanomaterials.
2. Ethical Considerations: Ethical guidelines are also a significant aspect of restrictions. Issues like privacy concerns, human enhancement, and equity are scrutinized to ensure that technological advancements do not lead to societal disparities or ethical dilemmas.
3. Environmental Regulations: The impact of nanomaterials on the environment is carefully regulated. For example, the disposal of nanomaterials and their possible accumulation in ecosystems are aspects that are tightly controlled to prevent long-term environmental damage.
