Mối liên hệ giữa từ thiết kế đến từ các hạt nano tạo ra sự cần thiết phân biệt tách các hạt này từ các hạt có kích thước tương tự sản xuất tự nhiên hoặc nhân tạo, chẳng hạn như những phát thải từ rừng hoả hoạn, xe có động cơ. Từ thiết kế phản ánh rằng các thành phần nguyên tử cố ý kết hợp để tạo ra vật liệu nano với độc đáo đặc tính lưu ý ở trên. Tuy nhiên, những kết hợp này có thể sản xuất vật liệu có đặc tính không thể đoán trước về tương tác của họ. | 8 Current and Proposed Approaches for Managing Risks in Occupational Environments Brenda E.

National and international governmental agencies companies and research organizations increasingly are recognizing the clear advantages of taking proactive steps both to understand the potential adverse health consequences of nanomaterials and to minimize the potential hazards from nanotechnology and nanomaterials in occupational environments National Nanotechnology Initiative 2006 OECD 2006 . An obvious benefit of this approach is avoiding the familiar history of identifying the negative health and environmental impacts of industrial and commercial materials only after years of their extensive .
